[PATCH] audit: dynamically allocate audit_names when not enough space is in the names array
Some system calls, such as loading a module, can cause filesystem activity such as creating lots of new files in /sys or debugfs. Audit can only capture 20 inodes in a single syscall since it stores them in a fixed length array. This patch shrinks the fixed length array to 5 names (the number used by a rename oper... 16 Mar 2010 17:24

[PATCH] x86/PCI: ignore Consumer/Producer bit and parse additional _CRS resources
We previously used only resources marked "Producer," i.e., those the bridge forwards downstream. But BIOSes haven't used that bit consistently, so it's useless. For bridge devices, we have to assume *all* ACPI resources are forwarded downstream. Non-Producer bridge resources typically appear in PCI config spac... 16 Mar 2010 17:24

[PATCH] x86/PCI: pci=use_crs regression fix
This patch fixes some PCI host bridge _CRS parsing problems and may fix Pete Zaitcev's http://bugzilla.kernel.org/show_bug.cgi?id=15533 regression, but I haven't seen any testing results yet. I'm pretty confident this will fix pci=use_crs on *some* machines even if Pete's problem turns out to be something else, s... 16 Mar 2010 17:24

[PATCH] audit: make filetype matching consistent with other filters
Every other filter that matches part of the inodes list collected by audit will match against any of the inodes on that list. The filetype matching however had a strange way of doing things. It allowed userspace to indicated if it should match on the first of the second name collected by the kernel. Name collect... 16 Mar 2010 17:24

no kernel events
Hi All, I'm puzzled by a machine where "udevadm monitor --kernel" reports nothing when items are connected/disconnected to USB. Only when I disconnect the USB-keyboard I get one disconnect event and nothing after. Reconnecting the keyboard leaves it unrecognized and dis-functional.

[PATCH 3/4] coredump: factor out put_cred() calls
Given that do_coredump() calls put_cred() on exit path, it is a bit ugly to do put_cred() + "goto fail" twice, just add the new "fail_creds" label.

[PATCH 4/4] coredump: shift down_write(mmap_sem) into coredump_wait()
- move the cprm.mm_flags checks up, before we take mmap_sem - move down_write(mmap_sem) and ->core_state check from do_coredump() to coredump_wait() This simplifies the code and makes the locking symmetrical.

[PATCH 2/4] coredump: cleanup "ispipe" code
- kill "int dump_count", argv_split(argcp) accepts argcp == NULL. - move "int dump_count" under " if (ispipe)" branch, fail_dropcount can check ispipe. - move "char **helper_argv" as well, change the code to do argv_free() right after call_usermodehelper_fns(). - If call_usermodehelper_fns() fails goto c... 16 Mar 2010 16:14
