The code that went into arch/ppc/kernel/signal.c recently to handle process freezing seems to contain a dubious assumption: that a process that calls do_signal when PF_FREEZE is set will have entered the kernel because of a system call. This patch removes that assumption. Signed-off-by:

This patch adds SELinux support for the KOBJECT_UEVENT Netlink family, so that SELinux can apply finer grained controls to it. For example, security policy for hald can be locked down to the KOBJECT_UEVENT Netlink family only. Currently, this family simply defaults to the default Netlink socket class. Note that some new permission definitions are added to sync with changes in the core userspace policy package, which auto-generates header files. Signed-off-by:

When we are not the real parent of the dst (e.g., when we're xfrm_dst and the child is an rtentry), it may already be on the GC list. In fact the current code is buggy to, we need to check dst->flags before the dec as dst may no longer be valid afterwards. Signed-off-by:

This recently got changed to include a lot of kernel internal stuff in the non-__KERNEL__ area of the header, which isn't so kosher and breaks libc builds. The fix is pretty simple. Signed-off-by:

Working on some code lately I've been getting huge values for "Cached". The cause is that get_page_cache_size() is an approximate value, and for a sufficiently small returned value of get_page_cache_size() the value underflows. Signed-off-by:

iscsi/lvm2/multipath needs guaranteed protection from the oom-killer, so make the magical value of -17 in /proc/<pid>/oom_adj defeat the oom-killer altogether. (akpm: we still need to document oom_adj and friends in Documentation/filesystems/proc.txt!) Signed-off-by:

We will return NULL from filemap_getpage when a page does not exist in the page cache and MAP_NONBLOCK is specified, here: page = find_get_page(mapping, pgoff); if (!page) { if (nonblock) return NULL; goto no_cached_page; } But we forget to do so when the page in the cache is not uptodate. The following could result in a blocking call: /* * Ok, found a page in the page cache, now we need to check * that it's up-to-date. */ if (!PageUptodate(page)) goto page_not_uptodate; Signed-off-by: -

This patch fixes a bug in the SELinux Netlink message type detection code, where the wrong constant was being used in a case statement. The incorrect value is not valid for this class of object so it would not have been reached, and fallen through to a default handler for all Netlink messages. Signed-off-by:

Fix the access-above-bottom-of-stack crash. 1. Allows to preserve the valueable optimization 2. Works for NMIs 3. Doesn't care whether or not there are more of the like instances where the stack is left empty. 4. Seems to work for me without the crashes:) (akpm: this is still under discussion, although I _think_ it's OK. You might want to hold off) Signed-off-by: Stas Sergeev <stsp@aknet.ru> Signed-off-by:

This was unexported by Arjan because we have no current users. However, during a conversion from tasklets to workqueues of the parisc led functions, we ran across a case where this was needed. In particular, the open coded equivalent of cancel_rearming_delayed_workqueue was implemented incorrectly, which is, I think, all the evidence necessary that this is a useful API. Signed-off-by:

In the deflate_[compress|uncompress|pcompress] functions we call the zlib_[in|de]flateReset function at the beginning. This is OK. But when we unload the deflate module we don't call zlib_[in|de]flateEnd to free all the zlib internal data. It looks like a bug for me. Please, consider the attached patch. Signed-off-by:

) From: Russell King <rmk+lkml@arm.linux.org.uk> ARM wasn't raising a SIGBUS with a siginfo structure. Fix __do_user_fault() to allow us to use it for SIGBUS conditions, and arrange for the sigbus path to use this. We need to prevent the siginfo code being called if we do not have a user space context to call it, so consolidate the "user_mode()" tests. Thanks to Ian Campbell who spotted this oversight.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
