When waking up from the S3 state on the MacBookAir, the trackpad is found in a yet unknown state, unable to switch to the proper multitouch mode. The result is a frozen touchpad, and a flood of errors of the kind bcm5974: bad trackpad package, length: 8. This patch retracts the reset_resume method altogether, falling back on the generic unbind/rebind functionality of the usb layer until further investigations can be made as how to reset the device when booting from efi.

This causes ecryptfs_crypt_stat.num_header_bytes_at_front to be 0, since there is no header data at the front of the file. This results in too much memory being requested and ENOMEM being returned from ecryptfs_write_metadata(). This patch fixes the problem by using the num_header_bytes_at_front variable for specifying the max size of the metadata, despite whether it is stored in the header or xattr.

The intel_output naming is inherited from the UMS code, which had a structure of screen -> CRTC -> output. The DRM code has an additional notion of encoder/connector, so the structure is screen -> CRTC -> encoder -> connector. This is a useful structure for SDVO encoders which can support multiple connectors (each of which requires different programming in the one encoder and could be connected to different CRTCs), or for DVI-I, where multiple encoders feed into the connector for whether it's used for digital or analog. Most of our code is encoder-related, so transition it to talking about encoders before we start trying to distinguish connectors. This patch is produced by sed s/intel_output/intel_encoder/ over the driver.

That code assumes the dentry is unhashed, but a recent server-side change started returning NULL leases on lookup failure, causing the .snap dentry to be hashed and NULL by ceph_fill_trace(). This causes dentry hash chain corruption, or a dies when d_rehash() includes BUG_ON(!d_unhashed(entry)); So, avoid processing the NULL dentry lease if it the dentry matches the snapdir name in ceph_fill_trace(). That allows the lookup completion to properly bind it to the snapdir inode. BUG there if dentry is hashed to be sure.

However, we did run into problems when we went to write back the pages because the 'oldest' snapc is determined by the oldest cap_snap, and that may be the newer snapc that reflects the deletion. This caused confusion and an infinite loop in ceph_update_writeable_page(). Change the snapc checks to allow writeback of any snapc that is equal to OR older than the 'oldest' snapc. When there are no cap_snaps, we were also using the realm's latest snapc for writeback, which complicates ceph_put_wrbufffer_cap_refs(). Instead, use i_head_snapc, the most snapc used for the most recent ('head') data. This makes the writeback snapc (ceph_osd_request.r_snapc) _always_ match a capsnap or i_head_snapc. Also, in writepags_finish(), drop the snapc referenced by the _page_ and do not assume it matches the request snapc (it may not anymore).

This will cause a overflow in our check, so it will seem like we have _tons_ of free space, and we'll allow reservations to occur that will end up larger than the amount of space we have.

When initializaing the IOMMU, we attach devices to their domains before the IOMMU is fully (re)initialized. Attaching a device will issue some important invalidations. In the context of the newly kexec'd kdump kernel, the IOMMU may have stale cached data from the original kernel. Because we do the attach too early, the invalidation commands are placed in the new command buffer before the IOMMU is updated w/ that buffer. This leaves the stale entries in the kdump context and can renders device unusable. Simply enable the IOMMU before we do the attach.

Fix this by simply using probe_kernel_address() when we rewind the frame pointer.

We run into this problem with the PLLB on the at91: ohci-at91 disables the PLLB when going to suspend. The slowclock code however tries to do the same: It saves the PLLB register value and when restoring the value during resume, it waits for the PLLB to lock again. However the PLL will never lock and the loop would run into its timeout because the slowclock code just stored and restored an empty register. This fixes the problem by only restoring PLLA/PLLB when they were enabled at suspend time.

According to Arnaud, the lock succeeds the first time he opens the file (since we cannot do a delegated open) but then fails after we start using delegated opens. The following patch fixes it by ensuring that locking behaviour is governed by a per-filesystem capability flag that is initially set, but gets cleared if the server ever returns an OPEN without the NFS4_OPEN_RESULT_LOCKTYPE_POSIX flag being set.

However, this code is no longer necessary since the kernel now can do PCI resource management fine all by itself, so remove the old code. When removing the code, it becomes obvious that the mem_offset setting in the PCIcore driver was wrong, however this was masked by the fixup code before, except in a few cases involving yenta_socket. For BCM47xx, the correct offset is 0, and since this is the only device using PCIcore in host mode, the offset can simply be removed unconditionally.

Still missing are ELF headers and .eh_frame information. But it is enough to allow us to move signal trampolines off of the stack. Note that emulation of branch delay slots in the FPU emulator still requires the stack. We allocate a single page (the vdso) and write all possible signal trampolines into it. The stack is moved down by one page and the vdso is mapped into this space.

This is a follow on to the vdso patch. Since all processes now have signal trampolines permanently mapped, we can use those instead of putting the trampoline on the stack and invalidating the corresponding icache across all CPUs. We also get rid of a bunch of ICACHE_REFILLS_WORKAROUND_WAR code. [Ralf: GDB 7.1 which has the necessary modifications to allow backtracing over signal frames will supposedly be released tomorrow. The old signal frame format obsoleted by this patch exists in two variations, for sane processors and for those requiring ICACHE_REFILLS_WORKAROUND_WAR. So there was never a GDB which did support backtracing over signal frames on all MIPS systems. This convinved me this series should be applied and pushed upstream as soon as possible.] Signed-off-by: David Daney To: linux-mips@linux-mips.org Patchwork: http://patchwork.linux-mips.org/patch/974/ Signed-off-by: Ralf Baechle --- arch/mips/include/asm/abi.h | 6 ++- arch/mips/kernel/signal-common.h | 5 --- arch/mips/kernel/signal.c | 86 +++++++++------------------------------- arch/mips/kernel/signal32.c | 55 +++++++------------------ arch/mips/kernel/signal_n32.c | 26 +++--------- 5 files changed, 43 insertions(+), 135 deletions(-) diff --git a/arch/mips/include/asm/abi.h b/arch/mips/include/asm/abi.h index 1dd74fb..9252d9b 100644 --- a/arch/mips/include/asm/abi.h +++ b/arch/mips/include/asm/abi.h @@ -13,12 +13,14 @@ #include struct mips_abi { - int (* const setup_frame)(struct k_sigaction * ka, + int (* const setup_frame)(void *sig_return, struct k_sigaction *ka, struct pt_regs *regs, int signr, sigset_t *set);

All those functions are EXPORT_SYMBOL() so are meant to be allowed to be used by non-GPL kernel modules. These calls all take page protection as an argument which is normally a constant like PAGE_KERNEL. This commit causes all protection constants like PAGE_KERNEL to not be constants and instead to contain the GPL-only symbol _page_cachable_default. This means that all calls to __vmalloc(), vmap(), etc, cause non-GPL modules to fail to link with the complaint that they are trying to use the GPL-only symbol _page_cachable_default... Change EXPORT_SYMBOL_GPL(_page_cachable_default) to EXPORT_SYMBOL() for non-GPL modules that call __vmalloc(), vmap(), vm_map_ram() etc. Signed-off-by: Anton Altaparmakov Cc: Chris Dearman Cc: linux-mips@linux-mips.org Cc: linux-kernel@vger.kernel.org Patchwork: http://patchwork.linux-mips.org/patch/1084/ Signed-off-by: Ralf Baechle --- arch/mips/mm/cache.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/mips/mm/cache.c b/arch/mips/mm/cache.c index be8627b..12af739 100644 --- a/arch/mips/mm/cache.c +++ b/arch/mips/mm/cache.c @@ -133,7 +133,7 @@ void __update_cache(struct vm_area_struct *vma, unsigned long address, } unsigned long _page_cachable_default; -EXPORT_SYMBOL_GPL(_page_cachable_default); +EXPORT_SYMBOL(_page_cachable_default); static inline void setup_protection_map(void) { -- cgit v1.1 From 2844e49f5ea1ae75d2026ff128b145e3bd44134c Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Sat, 3 Apr 2010 10:59:52 +0100 Subject: MIPS: Big Sur: Make defconfig more useful.

This means that a reuse of an anon_vma from an adjacent vma will always guarantee that both vma's are associated not only with the same anon_vma, they will also have the same anon_vma chain (of just a single entry in this case). And since anon_vma re-use was the only case where the same anon_vma might be associated with different chains of anon_vma's, we now have the case that every vma that shares the same anon_vma will always also have the same chain. That makes it much easier to think about merging vma's that share the same anon_vma's: you can always just drop the other anon_vma chain in anon_vma_merge() since you know that they are always identical. This also splits up the function to validate the anon_vma re-use, and adds a lot of commentary about the possible races.

The page->mapping must be the case that works for everybody, not just the mapping that happened to page it in first. Here's the scenario: - page gets allocated/mapped by process A. Let's call the anon_vma we associate the page with 'A' to keep it easy to track. - Process A forks, creating process B. The anon_vma in B is 'B', and has a chain that looks like 'B' -> 'A'. Everything is fine. - Swapping happens. The page (with mapping pointing to 'A') gets swapped out (perhaps not to disk - it's enough to assume that it's just not mapped any more, and lives entirely in the swap-cache) - Process B pages it in, which goes like this: do_swap_page -> page = lookup_swap_cache(entry); ... set_pte_at(mm, address, page_table, pte); page_add_anon_rmap(page, vma, address); And think about what happens here! In particular, what happens is that this will now be the "first" mapping of that page, so page_add_anon_rmap() used to do if (first) __page_set_anon_rmap(page, vma, address); and notice what anon_vma it will use? It will use the anon_vma for process B! What happens then? Trivial: process 'A' also pages it in (nothing happens, it's not the first mapping), and then process 'B' execve's or exits or unmaps, making anon_vma B go away. End result: process A has a page that points to anon_vma B, but anon_vma B does not exist any more. This can go on forever. Forget about RCU grace periods, forget about locking, forget anything like that. The bug is simply that page->mapping points to an anon_vma that was correct at one point, but was _not_ the one that was shared by all users of that possible mapping. Changing it to always use the deepest anon_vma in the anonvma chain gets us to the safest model. This can be improved in certain cases: if we know the page is private to just this particular mapping (for example, it's a new page, or it is the only swapcache entry), we could pick the top (most specific) anon_vma. But that's a future optimization. Make it _work_ reliably first.

Because ceph sockets only get passed kernel pointers, there is no dependency from sk_lock -> mmap_sem. If we share the same class as other sockets, lockdep detects a circular dependency from mmap_sem (page fault) -> fs mutex -> sk_lock -> mmap_sem because dependencies are noted from both ceph and user contexts. Using a separate class prevents the sk_lock(ceph) -> mmap_sem dependency and makes lockdep happy.

This cache flush is explicit through flush_cache_kmaps() in flush_all_zero_pkmaps(), or through __cpuc_flush_dcache_area() in kunmap_atomic(). There is also an implicit flush of those highmem pages that were part of a process that just terminated making those pages free as the whole VIVT cache has to be flushed on every task switch. Hence unmapped highmem pages need no cache maintenance in that case. However unmapped pages may still be cached with a VIPT cache because the cache is tagged with physical addresses. There is no need for a whole cache flush during task switching for that reason, and despite the explicit cache flushes in flush_all_zero_pkmaps() and kunmap_atomic(), some highmem pages that were mapped in user space end up still cached even when they become unmapped. So, we do have to perform cache maintenance on those unmapped highmem pages in the context of DMA when using a VIPT cache. Unfortunately, it is not possible to perform that cache maintenance using physical addresses as all the L1 cache maintenance coprocessor functions accept virtual addresses only. Therefore we have no choice but to set up a temporary virtual mapping for that purpose. And of course the explicit cache flushing when unmapping a highmem page on a system with a VIPT cache now can go, which should increase performance. While at it, because the code in __flush_dcache_page() has to be modified anyway, let's also make sure the mapped highmem pages are pinned with kmap_high_get() for the duration of the cache maintenance operation. Because kunmap() does unmap highmem pages lazily, it was reported by Gary King that those pages ended up being unmapped during cache maintenance on SMP causing segmentation faults.

McKenney" Date: Fri, 9 Apr 2010 15:39:10 -0700 Subject: rcu: Add rcu_access_pointer and rcu_dereference_protected This patch adds variants of rcu_dereference() that handle situations where the RCU-protected data structure cannot change, perhaps due to our holding the update-side lock, or where the RCU-protected pointer is only to be fetched, not dereferenced. These are needed due to some performance concerns with using rcu_dereference() where it is not required, aside from the need for lockdep/sparse checking. The new rcu_access_pointer() primitive is for the case where the pointer is be fetch and not dereferenced. This primitive may be used without protection, RCU or otherwise, due to the fact that it uses ACCESS_ONCE(). The new rcu_dereference_protected() primitive is for the case where updates are prevented, for example, due to holding the update-side lock. This primitive does neither ACCESS_ONCE() nor smp_read_barrier_depends(), so can only be used when updates are somehow prevented. Suggested-by: David Howells Signed-off-by: Paul E.

I didn't revert the register mapping, so we still use the same calling convention as kvm. KVM in more recent incarnations stopped injecting a fault when a guest tried to use the VMCALL instruction from ring 1, so lguest under kvm fails to make hypercalls. It was nice to share code with our KVM cousins, but this was overreach.

There is existing kernel code that uses a larger precision. An example from the audit code: vsnprintf(...,..., " msg='%.1024s'", (char *)data); which overflows precision and truncates to nothing. Extending precision size fixes the audit system issue. Other changes: Change the size of the struct printf_spec.type from u16 to u8 so sizeof(struct printf_spec) stays as small as possible. Reorder the struct members so sizeof(struct printf_spec) remains 64 bits without alignment holes. Document the struct members a bit more.

Unfortunately the sync code was unknowingly relying on this call to make sure metadata buffers were flushed via a xfs_buftarg_flush() call to move the tail of the log forward in memory before the final transactions of the sync process were issued. As a result, the old code would write a very recent log tail value to the log by the end of the sync process, and so a subsequent crash would leave nothing for log recovery to do. Hence in qa test 182, log recovery only replayed a small handle for inode fsync transactions in this case. However, with the removal of the extra ->sync_fs call, the log tail was now not moved forward with the inode fsync transactions near the end of the sync procese the first (and only) buftarg flush occurred after these transactions went to disk. The result is that log recovery now sees a large number of transactions for metadata that is already on disk. This usually isn't a problem, but when the transactions include inode chunk allocation, the inode create transactions and all subsequent changes are replayed as we cannt rely on what is on disk is valid. As a result, if the inode was written and contains unlogged changes, the unlogged changes are lost, thereby violating sync semantics. The fix is to always issue a transaction after the buftarg flush occurs is the log iѕ not idle or covered. This results in a dummy transaction being written that contains the up-to-date log tail value, which will be very recent. Indeed, it will be at least as recent as the old code would have left on disk, so log recovery will behave exactly as it used to in this situation.

This can cause an issue at the event recipient. An example of this is when cfg80211 sends IWEVASSOCREQIE and IWEVASSOCRESPIE events with NULL event body to wpa_supplicant. The wpa_supplicant overwrites the assoc request and assoc response IEs for this station with NULL data. If the association is WPA/WPA2, the wpa_supplicant is not able to generate EAPOL handshake messages, since the IEs are NULL. With the patch, req_ie and resp_ie will be NULL by avoiding the assignment if the driver has not sent the IEs to cfg80211. The event sending code sends the events only if resp_ie and req_ie are not NULL. This will ensure that the events are not sent with NULL event body.

Since the memory was already DMA mapped _before_ the call to write_tx_desc the device didn't get the txwi data at all or only sporadically. The call order is basically as follows (from rt2x00queue.c): 1) write_tx_data 2) rt2x00queue_map_txskb 3) write_tx_desc Hence, we shouldn't touch the skb in write_tx_desc anymore. To fix this issue create a new rt2800pci_write_tx_data callback and use it for updating the txwi _before_ the memory gets DMA mapped. The tx descriptor is still written (as before) in write_tx_desc. This patch allows basic TX on an rt305x soc device but I'm pretty sure that it will fix pci based cards as well. I can associate just fine with an AP now but I wasn't able to get a wpa secured connection working yet. Signed-off-by: Helmut Schaa Acked-by: Gertjan van Wingerde Signed-off-by: John W.

Rodriguez" Date: Thu, 15 Apr 2010 17:38:13 -0400 Subject: ath9k_hw: remove wrapper ath9k_hw_write_regs() This is used only once by ath9k_hw_process_ini() to write an array of phy registers through REG_WRITE_ARRAY(), but we already call REG_WRITE_ARRAY() multiple times on the same caller so just remove this pointless wrapper. We'll eventually just move the ath9k_hw_process_ini() caller as an callback to abstract away between different hardware families. Although this change is subtle I should note that this does change the delay pattern on writing the next series of registers. REG_WRITE_ARRAY() uses a counter for each register write and does a udelay(1) every 64 writes. By removing this call it means that the counter is processed for all the iniBB_RfGain registers and is incremented on ath9k_hw_process_ini(), before this the after the call ath9k_hw_write_regs() was made the register counter was kept at the same index number prior to the call.

The goal is to remove the dependency of ar9002_phy.h on calib.c This also adds stubs to be filled for AR9003 calibration code. Signed-off-by: Luis R. Rodriguez Signed-off-by: John W.

This was good while a random high-enough value was used which did not conflict with any of the already existing enum eeprom_param values. With AR9003 support the enums overlap and it means we either increment the random offset or just restore the reading logic to match what the HAL has. I choose to do the later to synchronize the logic on both code bases. This should fix reading the MAC address from the EEPROM on AR9003 hardware. Signed-off-by: Luis R.

It has been tested in an IBSS network where artifical IBSS merges have been done in order to trigger hundreds of rollover for the TSF lower part. It follows the logic mentionned by Derek, with only 2 register reads needed at each additional steps instead of 3 (the minimum number of register reads is still 3).

However TI recommends using deditated IRQ line for SDIO too. Add support for using dedicated interrupt line with SDIO, but also leave ability to switch to SDIO interrupts in case it's needed.

These two lines should not be there as af_inet and af_packet are namespace aware since a long time now.

Such disabling happens in NMIs and in other situations where lockdep might expect to recurse on itself. This patch therefore checks current->lockdep_recursion, disabling RCU lockdep splats when this variable is non-zero. In addition, this patch removes the "likely()", as suggested by Lai Jiangshan.

If the caller doesn't instantiate it, it's freed immediately at dput(). ->readdir reads directly from the dcache and depends on the dentries being hashed. When an ecryptfs mount is mounted, it associates the lower file and dentry with the ecryptfs files as they're accessed. When it's umounted and destroys all the in-memory ecryptfs inodes, it fput's the lower_files and d_drop's the lower_dentries. Commit 4981e081 added this and a d_delete in 2008 and several months later commit caeeeecf removed the d_delete. I believe the d_drop() needs to be removed as well. The d_drop effectively hides any file that has been accessed via ecryptfs from the underlying tmpfs since it depends on it being hashed for it to be accessible. I've removed the d_drop on my development node and see no ill effects with basic testing on both tmpfs and persistent storage. As a side effect, after ecryptfs d_drops the dentries on tmpfs, tmpfs BUGs on umount. This is due to the dentries being unhashed. tmpfs->kill_sb is kill_litter_super which calls d_genocide to drop the reference pinning the dentry. It skips unhashed and negative dentries, but shrink_dcache_for_umount_subtree doesn't. Since those dentries still have an elevated d_count, we get a BUG(). This patch removes the d_drop call and fixes both issues.

This caused more dependence on current state to ensure driver will be notified when configuration changes occur. One such problem arises if off-channel is in progress when HT information changes. Since HT is only enabled on the "oper_channel" the driver will never be notified of this change. Usually the driver is notified soon after of a BSS information change (BSS_CHANGED_HT) ... but since the driver did not get a notification that this is a HT channel the new BSS information does not make sense. Fix this by also changing the off-channel information when HT is enabled and thus cause driver to be notified correctly. This fixes a problem in 4965 when associated with 5GHz 40MHz channel.

Adding exclusively owned anonymous pages to the top anon_vma reduces rmap scanning overhead, especially in workloads with forking servers. This patch adds a parameter to __page_set_anon_rmap that can be used to indicate whether or not the added page is exclusively owned by the current process. Pages added through page_add_new_anon_rmap are exclusively owned by the current process, and can be added to the top anon_vma. Pages added through page_add_anon_rmap can be either shared or exclusively owned, so we do the conservative thing and add it to the oldest anon_vma. A next step would be to add the exclusive parameter to page_add_anon_rmap, to be used from functions where we do know for sure whether a page is exclusively owned.

The detailed phenomenon is 1. After a while the clients connected to one of these VAPs will get into a state that no broadcast/multicast packets can be transfered successfully while the unicast packets can be transfered normally. 2. Minutes latter the unitcast packets transfer will fail as well, because the ARP entry is expired and it can't be freshed due to the broadcast trouble. It's caused by the group key overwritten and someone discussed this issue in ath9k-devel maillist before, but haven't work out a fix yet. I referred the method in madwifi, and made a patch for ath9k. The method is to set the high bit of the sender(AP)'s address, and associated that mac and the group key. It requires the hardware supports multicast frame key search. It seems true for AR9160. Not sure whether it's the correct way to fix this issue. But it seems to work in my test. The patch is attached, feel free to revise it. Signed-off-by: Daniel Yingqiang ma Signed-off-by: John W.

This is currently partially the case. As it seems, when a probe-response is received from the AP the timer is still restarted, thus restarting the host based connection keep-alive mechanism. These probe-responses happen at least when scanning while associated. Fix this by preventing starting of the ieee80211_sta_conn_mon_timer in the ieee80211_rx_mgmt_probe_resp function.

Due to some merge issues with the uname refactoring patches we ended up calling the old uname version for both the old and new system call slots, which lead to the domainname filed never be set which caused failures with libnss_nis.

Actually, there is code there trying to set the transport header properly, but it sets it for the wrong skb ('skb' instead of 'buff'). This bug was introduced by commit a8fdf2b331b38d61fb5f11f3aec4a4f9fb2dedcb ("ipv6: Fix tcp_v6_send_response(): it didn't set skb transport header") Signed-off-by: Herbert Xu Signed-off-by: David S.

After receiving a ICMPv6 Too Big message reporting PMTU is less than the IPv6 Minimum Link MTU, sctp *can't* send any data/control chunk that total length including IPv6 head and IPv6 extend head is less than IPV6_MIN_MTU(1280 bytes).

If a sender binds to a particular NIC (SO_BINDTODEVICE), the outgoing traffic is being sent via the first found. The bonded device is thus not taken into an account during the routing. From the ip6_route_output function: If the binding address is multicast, linklocal or loopback, the RT6_LOOKUP_F_IFACE bit is set, but not for global address. So binding global address will neglect SO_BINDTODEVICE-binded device, because the fib6_rule_lookup function path won't check for the flowi::oif field and take first route that fits.

When capturing packets on a PF_PACKET/SOCK_RAW socket bound to all interfaces, there doesn't appear to be a way for the filter program to actually find out the underlying hardware type the packet was captured on.

This will be used to add support for multicast route dumping from all tables as the proc interface can't be extended to support anything but the main table without breaking compatibility. This partialy undoes the patch to introduce independant families for routing rules and converts ipmr routing rules to a new rtnetlink family.

At least some b43 devices are 'in the wild' that don't have SPROMs at all. When the SSB bus support loads, it attempts to read these (non-existant) SPROMs and causes hard hangs on the box -- no console output, etc. This patch adds some intelligence to determine whether or not the SPROM is present before attempting to read it. This avoids those hard hangs on those devices with no SPROM attached to their SSB bus. The SSB-attached devices (e.g. b43, et al.) won't work, but at least the box will survive to test further patches. :-) Signed-off-by: John W.

However, for hardware drivers with IEEE80211_HW_HAS_RATE_CONTROL this is not performed, as the rate control algorithm is not executed, and because the used rate is not known before the frame has actually been transmitted. This causes atleast a fixed 1Mb/s to be reported to user space. A few other instances of code also rely on this information. Fix this by setting the sta->last_tx_rate in tx_status handling. There, look for last rates entry set by the driver, and use that as value for sta->last_tx_rate. Signed-off-by: Juuso Oikarinen Signed-off-by: John W.

Quoting from the changelog: This patch does it the same way, except that it also prioritize rx data processing, simply because tx routines *can* wait. This is causing an issue with us referencing already freed memory, because some skb's we transmit, we immediately receive back, such as those for reading the eeprom (*) and getting stats. What can happen because of the moving of the tx processing to after the rx processing is that when the tasklet first runs after doing a special skb tx (such as eeprom) we've already received the answer to it. Then the rx processing ends up calling p54_find_and_unlink_skb to find the matching tx skb for the just received special rx skb and frees the tx skb. Then after the processing of the rx skb answer, and thus freeing the tx skb, we go process the completed tx ring entires, and then dereference the free-ed skb, to see if it should free free-ed by p54p_check_tx_ring()."

For standard frames, 82573/82574/82583 can enable L1 but L0s must be disabled, and for jumbo frames 82573/82574 must disable L1. This allows for some parts to enable L1 in certain configurations leading to better power savings. Also according to the same errata, Early Receive (ERT) should be disabled on 82573 when using jumbo frames.

This patch fixes it by checking the timestamp of the last received data packet too when the keepalive timer expires.

This disables writeback batching and anything else that relies upon a delayed interrupt. This patch enables the feature of "override" when a user sets rx-usecs to zero, the driver will respect that setting over using RSC, and automatically disable RSC. If rx-usecs is used to set the EITR value to 0, then the driver should disable LRO (aka RSC) internally until EITR is set to non-zero again.

If the dev_watchdog() timer fires during this time it is possible for a false tx timeout to occur. This patch moves the netif_carrier_off() so that it is called before the tx queues are stopped preventing the dev_watchdog timer from detecting false tx timeouts. The race is seen occosionally when FCoE or DCB settings are being configured or changed. Testing note, running ifconfig up/down will not reproduce this issue because dev_open/dev_close call dev_deactivate() and then dev_activate().

It has been reported that under certain heavy traffic conditions in MSI-X mode, the driver can lose an MSI-X vector causing all packets in the associated rx/tx ring pair to be dropped. The problem is caused by the chip dropping the write to unmask the MSI-X vector by the kernel (when migrating the IRQ for example). This can be prevented by increasing the GRC timeout value for these register read and write operations. Thanks to Dell for helping us debug this problem.

The bonding driver calls ndo_vlan_rx_register() while holding bond->lock. The bnx2 driver calls bnx2_netif_stop() to stop the rx handling while changing the vlgrp. The call also stops the cnic driver which sleeps while the bond->lock is held and cause the warning. This code path only needs to stop the NAPI rx handling while we are changing the vlgrp. Since no reset is going to occur, there is no need to stop cnic in this case. By adding a parameter to bnx2_netif_stop() to skip stopping cnic, we can avoid the warning.

We should add backlog size and receive_queue size (aka rmem_alloc) to pace writers, and let user run without being slow down too much. Introduce a sk_rcvqueues_full() helper, to avoid taking socket lock in stress situations. Under huge stress from a multiqueue/RPS enabled NIC, a single flow udp receiver can now process ~200.000 pps (instead of ~100 pps before the patch) on a 8 core machine.

To do this the pci_dev pointer that was in the rings has been replaced with a device pointer, and as a result all references to [tr]x_ring->pdev have been replaced with [tr]x_ring->dev.

Summary of the changes: 1. Improved error handling. 2. Added the missing timeout arguments to usb_control_msg(). The following is a new Linux driver which exposes certain models of Sierra Wireless modems to the operating system as Network Interface Cards (NICs). This driver requires a version of the sierra.c driver which supports blacklisting to work properly. The blacklist in sierra.c rejects the interfaces claimed by sierra_net.c. Likewise, the sierra_net.c driver only accepts (i.e. whitelists) the interface(s) used for USB-to-WWAN traffic. The version of sierra.c which supports blacklisting is available from the sierra wireless knowledge base page for older kernels. It is also available in Linux kernel starting from version 2.6.31. This driver works with all Sierra Wireless devices configured with PID=68A3 like USB305, USB306 provided the corresponding firmware version is I2.0 (for USB305) or M3.0 (for USB306) and later. This driver will not work with earlier firmware versions than the ones shown above. In this case the driver will issue an error message indicating incompatibility and will not serve the device's USB-to-WWAN interface. Sierra_net.c sits atop a pre-existing Linux driver called usbnet.c. A series of hook functions are provided in sierra_net.c which are called by usbnet.c in response to a particular condition such as receipt or transmission of a data packet. As such, usbnet.c does most of the work of making a modem appear to the system as a network device and for properly exchanging traffic between the USB subsystem and the Network card interface. Sierra_net.c is concerned with managing the data exchanged between the USB-to-WWAN interface and the upper layers of the operating system.

Due to this the function cfcnfg_linkdestroy_rsp does nothing anymore. o Because disconnect may take down a connection before a connect response is received the function cfcnfg_linkup_rsp is checking if the client is still waiting for the response, if not a disconnect request is sent to the modem. o cfctrl is no longer keeping track of pending disconnect requests. o Added function cfctrl_cancel_req, which is used for deleting a pending connect request if disconnect is done before connect response is received. o Removed unused function cfctrl_insert_req2 o Added better handling of connect reject from modem.

Making the socket implementation more aligned with the other socket layers and using more of the support functions available in sock.c. Lots of code is copied from af_unix (and some from af_irda). Non-blocking mode should be working as well. Signed-off-by: Sjur Braendeland Signed-off-by: David S.

In the first category are "fast" commands, these mostly take only 0 or 1 polls to complete, but occasionally upto 50 (giving a 0.5ms execution time.) In the second category, the command completion takes well more than 0.5ms (from 1.5ms upwards.) This patch fixes command polling such that it is optimal for the fast commands, but also allows sleep for the longer ones.

After associated scans, the mac80211 does re-set the current channel, causing the join to occur. This would stop the hardware keep alive. To make the joins safer in this respect, this patch adds a join function that does the hardware-keep-alive magic along the join.

This is how they are implemented and what it says in the DebugFS documentation. DebugFS can not be compiled as a module. As a result, we only need to check for error pointers and particularly -ENODEV one time to know that DebugFS is enabled. This patch keeps the first check for error pointers and removes the rest. The other reason for this patch, is that it silences some Smatch warnings. Smatch sees the condition "(result != -ENODEV)" and assumes that it's possible for "result" to equal -ENODEV. If it were possible it would lead to an error pointer dereference. But since it's not, we can just remove the check. Signed-off-by: Dan Carpenter Signed-off-by: John W.

The problem is in sctp_process_unk_param: if (NULL == *errp) *errp = sctp_make_op_error_space(asoc, chunk, ntohs(chunk->chunk_hdr->length)); if (*errp) { sctp_init_cause(*errp, SCTP_ERROR_UNKNOWN_PARAM, WORD_ROUND(ntohs(param.p->length))); sctp_addto_chunk(*errp, WORD_ROUND(ntohs(param.p->length)), param.v); When we allocate an error chunk, we assume that the worst case scenario requires that we have chunk_hdr->length data allocated, which would be correct nominally, given that we call sctp_addto_chunk for the violating parameter. Unfortunately, we also, in sctp_init_cause insert a sctp_errhdr_t structure into the error chunk, so the worst case situation in which all parameters are in violation requires chunk_hdr->length+(sizeof(sctp_errhdr_t)*param_count) bytes of data. The result of this error is that a deliberately malformed packet sent to a listening host can cause a remote DOS, described in CVE-2010-1173: http://cve.mitre.org/cgi-bin/cvename.cgi?name=2010-1173 I've tested the below fix and confirmed that it fixes the issue. We move to a strategy whereby we allocate a fixed size error chunk and ignore errors we don't have space to report.

This added latency because of possible backlog handling. Then later, ticket spinlocks added yet another latency source in case of DDOS. This patch introduces lock_sock_bh() and unlock_sock_bh() synchronization primitives, avoiding one atomic operation and backlog processing. skb_free_datagram_locked() uses them instead of full blown lock_sock()/release_sock(). skb is orphaned inside locked section for proper socket memory reclaim, and finally freed outside of it.

The comments in mac80211.h show there are actually three different, relevant variables, of which we are currently using two, both incorrectly. Fix this by making - ampdu_ack_len -> the number of ACKed frames (i.e. successes) - ampdu_ack_map -> the bitmap - ampdu_len -> the total number of frames sent (i.e., attempts) to match the header file (and verified with ath9k's usage) and updating Intel's RS code to match.

The MBM devices are instead identified by GUID. In order for cdc_ether to handle these devices the GUID in the MDLM descriptor is tested. All MBM devices currently handled by cdc_ether as well as future CDC Ethernet MBM devices can be identified by the GUID. This is the same solution used in Carl Nordbeck's mbm driver, http://kerneltrap.org/mailarchive/linux-usb/2008/11/17/4141384/thread I post this as RFC to get feedback on however cdc_ether is the correct place to do the binding, or if it should be done in a separate driver, e.g. zaurus.

RCU conversion is pretty much needed : 1) Add a new structure, called "struct socket_wq" to hold all fields that will need rcu_read_lock() protection (currently: a wait_queue_head_t and a struct fasync_struct pointer). [Future patch will add a list anchor for wakeup coalescing] 2) Attach one of such structure to each "struct socket" created in sock_alloc_inode(). 3) Respect RCU grace period when freeing a "struct socket_wq" 4) Change sk_sleep pointer in "struct sock" by sk_wq, pointer to "struct socket_wq" 5) Change sk_sleep() function to use new sk->sk_wq instead of sk->sk_sleep 6) Change sk_has_sleeper() to wq_has_sleeper() that must be used inside a rcu_read_lock() section. 7) Change all sk_has_sleeper() callers to : - Use rcu_read_lock() instead of read_lock(&sk->sk_callback_lock) - Use wq_has_sleeper() to eventually wakeup tasks. - Use rcu_read_unlock() instead of read_unlock(&sk->sk_callback_lock) 8) sock_wake_async() is modified to use rcu protection as well. 9) Exceptions : macvtap, drivers/net/tun.c, af_unix use integrated "struct socket_wq" instead of dynamically allocated ones. They dont need rcu freeing. Some cleanups or followups are probably needed, (possible sk_callback_lock conversion to a spinlock for example...). Signed-off-by: Eric Dumazet Signed-off-by: David S.

Tsirkin" Date: Wed, 17 Mar 2010 17:45:01 +0200 Subject: tun: add ioctl to modify vnet header size virtio added mergeable buffers mode where 2 bytes of extra info is put after vnet header but before actual data (tun does not need this data). In hindsight, it would have been better to add the new info *before* the packet: as it is, users need a lot of tricky code to skip the extra 2 bytes in the middle of the iovec, and in fact applications seem to get it wrong, and only work with specific iovec layout. The fact we might need to split iovec also means we might in theory overflow iovec max size. This patch adds a simpler way for applications to handle this, and future proofs the interface against further extensions, by making the size of the virtio net header configurable from userspace.

The original orinoco_usb patches had a boolean variable controlling whether spin_lock_bh was used, or irq based locking. This version provides wrappers for the lock functions and the drivers specify the functions pointers needed. This will introduce a performance penalty, but I'm not expecting it to be noticable.

The low level hermes routines (for local bus cards) are replaced, the driver supplies its own ndo_xmit_start function, and locking is done with the _bh variant. Some recent functionality is not available to the USB cards yet (firmware loading and WPA). Out-of-tree driver originally written by Manuel Estrada Sainz.

It is very useful for debugging session initiation and teardown problems since with this you don't have to force a lot of traffic to get aggregation and thus have less data to analyse. Also, to debug mac80211 code itself, make hwsim "support" aggregation sessions. It will still just transfer the frame, but go through the setup and teardown handshakes.

This makes sense if the BSSID isn't also fixed, but it need not scan all channels -- just one is sufficient. Make it do that by moving the scan setup code to ieee80211_request_internal_scan() and include a channel variable setting.

Michael Planes recently encountered a 'KY-RS9600 USB-LAN converter', which came with a driver CD containing a Linux driver. This driver turns out to be a copy of dm9601.c with symbols renamed and my copyright stripped. That aside, it did contain 1 functional change in dm_write_shared_word(), and after checking the datasheet the original value was indeed wrong (read versus write bits). On Michaels HW, this change bumps receive speed from ~30KB/s to ~900KB/s. On other devices the difference is less spectacular, but still significant (~30%).

(~130.000 IPI per second) - SLAB allocator (faster than SLUB in this workload) - tg3 NIC - 1.080.000 pps without a single drop at NIC level. Idea is to add two prefetchw() calls in __alloc_skb(), one to prefetch first sk_buff cache line, the second to prefetch the shinfo part. Also using one memset() to initialize all skb_shared_info fields instead of one by one to reduce number of instructions, using long word moves.

I already tested it for bridge, bonding, bridge over bonding, and bonding over bridge. It looks fine now. To make bridge and bonding support netpoll, we need to adjust some netpoll generic code. This patch does the following things: 1) introduce two new priv_flags for struct net_device: IFF_IN_NETPOLL which identifies we are processing a netpoll; IFF_DISABLE_NETPOLL is used to disable netpoll support for a device at run-time; 2) introduce one new method for netdev_ops: ->ndo_netpoll_cleanup() is used to clean up netpoll when a device is removed. 3) introduce netpoll_poll_dev() which takes a struct net_device * parameter; export netpoll_send_skb() and netpoll_poll_dev() which will be used later; 4) hide a pointer to struct netpoll in struct netpoll_info, ditto. 5) introduce ->real_dev for struct netpoll. 6) introduce a new status NETDEV_BONDING_DESLAE, which is used to disable netconsole before releasing a slave, to avoid deadlocks.

Given that we've had the ability to do emergency route cache rebuilds for awhile now, based on a statistical analysis of the various hash chain lengths in the cache, the use of the flush timer is somewhat redundant. This patch removes the rt_secret_interval sysctl, allowing us to rely solely on the statistical analysis mechanism to determine the need for route cache flushes.
