Since the big direct I/O rework do_truncate takes i_alloc_sem before calling into ->setattr. Unfortunately the other callers of ->setattr with ATTR_SIZE, most notably nfsd don't take it. The (out of tree) XFS dmapi code relies wants to release i_alloc_sem and thus gets into problems like http://oss.sgi.com/bugzilla/show_bug.cgi?id=365 This patch moves acquiring and releasing i_alloc_sem into notify_change() to make the locking behaviour consistant.

With Solar Designer <solar@openwall.com> The following patch changes the following on ELF parsing/loading code (fs/binfmt_elf): - Stronger validity checks on ELF files: treat e_phnum (program header count) < 1 as invalid treat p_filesz (file size) < 2 invalid on program header interp. case - Saner return error codes - Make sure SIGKILL is delivered on error handling Signed-off-by: -

This change still keeps the comm length at 16, but allows easier patching for local modifications, and also introduces a macro to use instead of magic 16, where sizeof(comm) is not preferable to use. Not able to use killall, pidof etc. effectively, when long process names are used for scripts. Just changing the command length from 16 to 32 breaks a.out coredump logic. Deamonise and get_task_comm helped in other places in 2.6.10. Signed-off-by:

A couple of one liners to resolve two issues that have come up regarding audit. Roger reported a problem with audit.c:audit_receive_skb which improperly negates the errno argument when netlink_ack is called. The second issue was reported by Steve on the linux-audit list, auditsc.s:audit_log_exit using %u instead of %d in the audit_log_format call. Please note, there is a mailing list available for audit discussion at https://www.redhat.com/archives/linux-audit/Signed-off-by:

x86_64 only delivers signals in the SA_INFO style, whether you ask for it or not. This patch adds a config option which says whether the arch is SA_INFO-only or not, and ifdefs out the sigcontext signal delivery if so. Signed-off-by:

In arch/um/kernel/skas/uaccess.c, the simple assignment va_list args = *((va_list *) arg_ptr); is used in do_buffer_op() to obtain a copy of a va_list, that was delivered as a pointer only. But this construction doesn't compile on s390. Instead, va_copy() and va_end() should be used (see "man va_start"). Signed-off-by:

This patch makes UML produce error messages instead of silently exiting when one of several configuration mistakes are made. FD_CHAN is now mandatory so that people don't turn it off and complain about no boot messages. Some printks were turned into printfs in the tt mode gdb code so that they appear on the screen.

This is the three-level page table support from the x86_64 patch. It can be enabled on x86, although it's not particularly needed at this point. However, it can be used to implement very large physical memory (with almost all of it in highmem) on UML. Signed-off-by:

This factors out a bunch of non-generic system calls into i386-specific code. It also adds the x86_64-specific system calls. A couple of generic system calls handlers are declared in sysdep-i386 because x86 has no declarations for them, but x86_64 has incompatible ones.

Found by Bodo Stroesser. Description from Bodo: >> On i386, if a signal handler is started, the kernel saves the fpu-state of the interrupted routine in the sigcontext on the stack. Calling unlazy_fpu() and setting current->used_math=0, the kernel supplies the signal-handler with a cleared virtual fpu. On sigreturn(), the old fpu-state of the interrupted routine is restored. If a process never used the fpu, it virtually has a cleared fpu. If such a process is interrupted by a signal handler, no fpu-context is saved and sigcontext->fpstate is set to NULL. Assume, that the signal handler uses the fpu. Then, AFAICS, on sigreturn current->used_math will be 1. Since sigcontext->fpstate still is NULL, restore_sigcontext() doesn't call restore_i387(). Thus, no clear_fpu() is done, current->used_math is not reset. Now, the interrupted processes fpu no longer is cleared! << Fix by AK. Just clear the FPU again when this happens. patch for i386 and x86-64. Signed-off-by:
