Fix longstanding lock inversion in drop_pagecache_sb by dropping inode_lock before calling __invalidate_mapping_pages(). We just have to make sure inode won't go away from under us by keeping reference to it and putting the reference only after we have safely resumed the scan of the inode list. A bit tricky but not too bad... Signed-off-by:

This version brings a few fixes for the extern checks, and a couple of new checks. Of note: - false is now recognised as a 0 assignment in static/external assignments, - printf format strings including %L are reported, - a number of fixes for the extern in .c file detector which had temporarily lost its ability to detect variables; undetected due to the loss of its test. Andy Whitcroft (8): Version: 0.18 false should trip 0 assignment checks tests: reinstate missing tests tests: allow specification of the file extension for a test fix extern checks for variables check for and report %Lu, %Ld, and %Li ensure we only start a statement on lines with some content extern spacing Signed-off-by:Andy Whitcroft <apw@shadowen.org> Cc: Ingo Molnar <mingo@elte.hu> Signed-off-by:

This version brings improvements to external declaration detection, fixes to quote tracking, fixes to unary tracking, some clarification of wording, and the usual slew of fixes for false positives. Of note: - much better unary tracking across preprocessor directives - UTF8 checks highlight the character at fault - widening of mutex detection Andy Whitcroft (17): Version: 0.17 values: __attribute__ carries through the previous type quotes: should only follow "positive" lines clarify the indent tabs over spaces wording loosen NR_CPUS check for array range initialisers detect external function declarations without an extern prefix function declaration arguments should be with the identifier DEFINE_MUTEX should report in line with struct mutex NR_CPUS is valid in preprocessor statements comment detection should not start on the @@ line types: add support for #undef tighten mutex/completion reports to usage allow export of function pointers values: preprocessor #define is out of line maintain values values: #define does not always have parentheses unary '*' may be const utf8 checks should report location of the invalid character Wolfram Sang (1): make checkpatch.pl really skip <asm/irq.h> Signed-off-by: -

This can be triggered with root help only, but... Register the ":text:E::txt::/root/cat.txt:' rule in binfmt_misc (by root) and try launching the cat.txt file (by anyone) :) The result is - the endless recursion in the load_misc_binary -> open_exec -> load_misc_binary chain and stack overflow. There's a similar problem with binfmt_script, and there's a sh_bang memner on linux_binprm structure to handle this, but simply raising this in binfmt_misc may break some setups when the interpreter of some misc binaries is a script. So the proposal is to turn sh_bang into a bit, add a new one (the misc_bang) and raise it in load_misc_binary. After this, even if we set up the misc -> script -> misc loop for binfmts one of them will step on its own bang and exit. Signed-off-by:

SysRQ-P is not always useful on SMP systems, since it usually ends up showing the backtrace of a CPU that is doing just fine, instead of the backtrace of the CPU that is having problems. This patch adds SysRQ show-all-cpus(L), which shows the backtrace of every active CPU in the system. It skips idle CPUs because some SMP systems are just too large and we already know what the backtrace of the idle task looks like. [akpm@linux-foundation.org: coding-style fixes] Signed-off-by:

I noticed that 2.6.24.2 calculates bprm->argv_len at do_execve(). But it doesn't update bprm->argv_len after "remove_arg_zero() + copy_strings_kernel()" at load_script() etc. audit_bprm() is called from search_binary_handler() and search_binary_handler() is called from load_script() etc. Thus, I think the condition check if (bprm->argv_len > (audit_argv_kb << 10)) return -E2BIG; in audit_bprm() might return wrong result when strlen(removed_arg) != strlen(spliced_args). Why not update bprm->argv_len at load_script() etc. ? By the way, 2.6.25-rc3 seems to not doing the condition check. Is the field bprm->argv_len no longer needed?

Almost all implementations of pci_iomap() in the kernel, including the generic lib/iomap.c one, copies the content of a struct resource into unsigned long's which will break on 32 bits platforms with 64 bits resources. This fixes all definitions of pci_iomap() to use resource_size_t. I also "fixed" the 64bits arch for consistency. Signed-off-by:
