* MFP4: Support for profiling dynamically loaded objects.jkoshy2006-03-263-26/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Kernel changes: Inform hwpmc of executable objects brought into the system by kldload() and mmap(), and of their removal by kldunload() and munmap(). A helper function linker_hwpmc_list_objects() has been added to "sys/kern/kern_linker.c" and is used by hwpmc to retrieve the list of currently loaded kernel modules. The unused `MAPPINGCHANGE' event has been deprecated in favour of separate `MAP_IN' and `MAP_OUT' events; this change reduces space wastage in the log. Bump the hwpmc's ABI version to "2.0.00". Teach hwpmc(4) to handle the map change callbacks. Change the default per-cpu sample buffer size to hold 32 samples (up from 16). Increment __FreeBSD_version. libpmc(3) changes: Update libpmc(3) to deal with the new events in the log file; bring the pmclog(3) manual page in sync with the code. pmcstat(8) changes: Introduce new options to pmcstat(8): "-r" (root fs path), "-M" (mapfile name), "-q"/"-v" (verbosity control). Option "-k" now takes a kernel directory as its argument but will also work with the older invocation syntax. Rework string handling in pmcstat(8) to use an opaque type for interned strings. Clean up ELF parsing code and add support for tracking dynamic object mappings reported by a v2.0.00 hwpmc(4). Report statistics at the end of a log conversion run depending on the requested verbosity level. Reviewed by: jhb, dds (kernel parts of an earlier patch) Tested by: gallatin (earlier patch)

This avoids the creation of runs that are incompletely utilized, as long as pagesize isn't too large (>32kB, given the current RUN_MIN_REGS_2POW setting). Increase the size of several structure bitfields in arena_run_t in order to avoid integer overflow in the case that a run's header does not overlap with the space that is usable as application allocation regions. Given the tiny_min_2pow change, this fix has no additional impact unless pagesize is >32kB. Reported by: kris

| | | | | | | | | | | | | | | | | | | internally used chunk to start at the beginning of the heap, rather than at a chunk-aligned address. This reduces mapped memory somewhat for 32-bit architectures. Add the arena_run_link_t type and use it wherever a run object is only used as a ring 'header'. This saves approximately 40 kB of memory per arena. Remove an obsolete (no longer used) code path from base_alloc(), which supported the internal allocation of objects larger than the chunk size. Enhance chunk_dealloc() to cache chunk addresses for all deallocated chunks. This has no impact for most programs, but has the potential to reduce VM map fragmentation for programs that use huge allocations.

The actual 'len' limit is the maximum file size or what will fit in your address space, whichever comes first. It should be possible to make 1TB files on 32 bit systems, but of course address space runs out long before then.

| | | | | | | | | | | | | | | | | | | | | | This commit implements storing/reading POSIX.1e-style extended attribute information in "pax" format archives. An outline of the storage format is in the tar.5 manpage. The archive_read_extract() function has code to restore those archives to disk for Linux; FreeBSD implementation is forthcoming. Many thanks to Jaakko Heinonen for finding flaws in earlier proposals and doing the bulk of the coding in this work.
* | Update the resolver in libc to BIND9's one.ume2006-03-2142-7838/+369
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since, res_sendsigned(3) and the friends use MD5 functions, it is hard to include them without having MD5 functions in libc. So, res_sendsigned(3) is not merged into libc. Since, res_update(3) in BIND9 is not binary compatible with our res_update(3), res_update(3) is leaved as is, except some necessary modifications. The res_update(3) and the friends are not essential part of the resolver. They are not defined in resolv.h but defined in res_update.h separately in BIND9. Further, they are not called from our tree. So, I hide them from our resolv.h, but leave them only for binary backward compatibility (perhaps, no one calls them). Since, struct __res_state_ext is not exposed in BIND9, I hide it from our resolv.h. And, global variable _res_ext is removed. It breaks binary backward compatibility. But, since it is not used from outside of our libc, I think it is safe. Reviewed by: arch@ (no objection)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | allocation patterns that involve a relatively even mixture of many different size classes. Reduce the chunk size from 16 MB to 2 MB. Since chunks are now carved up using an address-ordered first best fit policy, VM map fragmentation is much less likely, which makes smaller chunks not as much of a risk. This reduces the virtual memory size of most applications. Remove redzones, since program buffer overruns are no longer as likely to corrupt malloc data structures. Remove the C MALLOC_OPTIONS flag, and add H and S.
