| * [PATCH] ipw2100: Fix dropping fragmented small packet problemZhu Yi2007-01-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | The rx_data.header struct is ieee80211_hdr_4addr. If a wireless frame uses ieee80211_hdr_3addr header and is less than 6 bytes, it will be discarded. This is not likely going to happen for normal packets (since there is TCP, IP headers). But if fragmentation is used, there will be such small trailing packets. And they will be lost for ever.

It adds the printer to the list of "quirky" printers. The printer seems not answer to ID requests some seconds after plugging in. Patch is based on linux-2.6.19.1. Background: As far as I could see (strace, usbmon), the Kyocera FS-820 answers to ID requests only a few seconds after plugging it in. This applies to detecting it with cups and is also true for the printing itself, which is initiated with an ID request. Since I have little usb knowledge, maybe someone can interpret the data, especially the fist bulk transfer - why request 8192 bytes? This is the second version of the patch. usbmon output of printing an email without patch: tail -F /tmp/printlog.txt c636e140 3374734463 S Bi:002:02 -115 8192 < c9d43b40 3374734494 S Ci:002:00 s a1 00 0000 0000 03ff 1023 < c9d43b40 3379732301 C Ci:002:00 -104 0 c636e140 3379733294 C Bi:002:02 -2 0 [...repeating...] with patch: tail -F /tmp/printlog.txt d9cb82c0 3729790131 S Ci:002:00 s a1 00 0000 0000 03ff 1023 < d9cb82c0 3729791725 C Ci:002:00 0 91 = 005b4944 3a46532d 3832303b 4d46473a 4b796f63 6572613b 434d443a 50434c58 df956320 3732493190 S Bo:002:01 -115 1347 = 1b252d31 32333435 5840504a 4c0a4050 4a4c2053 4554204d 414e5541 4c464545 [...more data...] Signed-off-by: Martin Williges <kernel@zut.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

| * | | | i2c-mv64xxx: Fix random oops at bootMaxime Bizon2007-01-051-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I have a Marvell board which has the same i2c hw block than mv64xxx, so I'm trying to use i2c-mv64xxx driver. But I get the following random oops at boot: Unable to handle kernel NULL pointer dereference at virtual address 00000002 Backtrace: [<c0397e4c>] (mv64xxx_i2c_intr+0x0/0x2b8) from [<c02879c4>] (__do_irq+0x4c/0x8c) [<c0287978>] (__do_irq+0x0/0x8c) from [<c0287c0c>] (do_level_IRQ+0x68/0xc0) r8 = C0501E08 r7 = 00000005 r6 = C0501E08 r5 = 00000005 r4 = C048BB78 [<c0287ba4>] (do_level_IRQ+0x0/0xc0) from [<c02885f8>] (asm_do_IRQ+0x50/0x134) r6 = C0449C78 r5 = F1020000 r4 = FFFFFFFF [<c02885a8>] (asm_do_IRQ+0x0/0x134) from [<c02869c4>] (__irq_svc+0x24/0x100) r8 = C1CAC400 r7 = 00000005 r6 = 00000002 r5 = F1020000 r4 = FFFFFFFF [<c0287efc>] (setup_irq+0x0/0x124) from [<c02880d0>] (request_irq+0xb0/0xd0) r7 = C041B2AC r6 = C0397E4C r5 = 00000000 r4 = 00000005 [<c0288020>] (request_irq+0x0/0xd0) from [<c03985f4>] (mv64xxx_i2c_probe+0x148/0x244) [<c03984ac>] (mv64xxx_i2c_probe+0x0/0x244) from [<c038bedc>] (platform_drv_probe+0x20/0x24) The oops is caused by a spurious interrupt that occurs when request_irq is called. mv64xxx_i2c_fsm() tries to read drv_data->msg, which is NULL. I noticed that hardware init is done after requesting irq. Thus any pending irq from previous hardware usage may cause this.

This was previously (wrongly) associated with the i2c_adapter.dev node. Sysfs based tools and libraries can start converting right away. - Issue a warning for legacy adapter drivers that don't provide any physical device node; so systems with those drivers will know to fix this problem earlier. This is one of a series of patches to help the I2C stack become a better citizen of the Linux Driver Model world.

For that matter, to get rid of that _option_ to initialize then, and always init that driver with subsystem_init() ... it's common with embedded systems to need I2C access to tweak a GPIO expander or do some other work when bringing up drivers, that's not specific to USB stacks. >> Signed-off-by: Vitaly Wool <vitalywool@gmail.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>

If you are using these, for example, to get notification about all tasks forking and exiting, you get multiple unaligned access errors per process. Use put_unaligned() in the appropriate palces to fix this.

This is unfortunate because the actual registers are 0x50 and 0x54. Fixing this offset cures the second channel problems reported. Secondly there are some problems with the HPT370 and certain ATA drives. The filter code however only filters ATAPI devices due to a reversed type check.
