-Subject: [PATCH 1/3] mm: larger stack guard gap, between vmas
-
-commit 1be7107fbe18eed3e319a6c3e83c78254b693acb upstream.
-
-Stack guard page is a useful feature to reduce a risk of stack smashing
-into a different mapping. We have been using a single page gap which
-is sufficient to prevent having stack adjacent to a different mapping.
-But this seems to be insufficient in the light of the stack usage in
-userspace. E.g. glibc uses as large as 64kB alloca() in many commonly
-used functions. Others use constructs liks gid_t buffer[NGROUPS_MAX]
-which is 256kB or stack strings with MAX_ARG_STRLEN.
-
-This will become especially dangerous for suid binaries and the default
-no limit for the stack size limit because those applications can be
-tricked to consume a large portion of the stack and a single glibc call
-could jump over the guard page. These attacks are not theoretical,
-unfortunatelly.
-
-Make those attacks less probable by increasing the stack guard gap
-to 1MB (on systems with 4k pages; but make it depend on the page size
-because systems with larger base pages might cap stack allocations in
-the PAGE_SIZE units) which should cover larger alloca() and VLA stack
-allocations. It is obviously not a full fix because the problem is
-somehow inherent, but it should reduce attack space a lot.
-
-One could argue that the gap size should be configurable from userspace,
-but that can be done later when somebody finds that the new 1MB is wrong
-for some special case applications. For now, add a kernel command line
-option (stack_guard_gap) to specify the stack gap size (in page units).
-
-Implementation wise, first delete all the old code for stack guard page:
-because although we could get away with accounting one extra page in a
-stack vma, accounting a larger gap can break userspace - case in point,
-a program run with "ulimit -S -v 20000" failed when the 1MB gap was
-counted for RLIMIT_AS; similar problems could come with RLIMIT_MLOCK
-and strict non-overcommit mode.
-
-Instead of keeping gap inside the stack vma, maintain the stack guard
-gap as a gap between vmas: using vm_start_gap() in place of vm_start
-(or vm_end_gap() in place of vm_end if VM_GROWSUP) in just those few
-places which need to respect the gap - mainly arch_get_unmapped_area(),
-and and the vma tree's subtree_gap support for that.

-
-commit bd726c90b6b8ce87602208701b208a208e6d5600 upstream.
-
-Fix expand_upwards() on architectures with an upward-growing stack (parisc,
-metag and partly IA-64) to allow the stack to reliably grow exactly up to
-the address space limit given by TASK_SIZE.

-Subject: [PATCH 3/3] mm: fix new crash in unmapped_area_topdown()
-
-commit f4cb767d76cf7ee72f97dd76f6cfa6c76a5edc89 upstream.
-
-Trinity gets kernel BUG at mm/mmap.c:1963! in about 3 minutes of
-mmap testing. That's the VM_BUG_ON(gap_end < gap_start) at the
-end of unmapped_area_topdown(). Linus points out how MAP_FIXED
-(which does not have to respect our stack guard gap intentions)
-could result in gap_end below gap_start there. Fix that, and
-the similar case in its alternative, unmapped_area().

-Subject: [PATCH 1/3] mm: larger stack guard gap, between vmas
-
-commit 1be7107fbe18eed3e319a6c3e83c78254b693acb upstream.
-
-Stack guard page is a useful feature to reduce a risk of stack smashing
-into a different mapping. We have been using a single page gap which
-is sufficient to prevent having stack adjacent to a different mapping.
-But this seems to be insufficient in the light of the stack usage in
-userspace. E.g. glibc uses as large as 64kB alloca() in many commonly
-used functions. Others use constructs liks gid_t buffer[NGROUPS_MAX]
-which is 256kB or stack strings with MAX_ARG_STRLEN.
-
-This will become especially dangerous for suid binaries and the default
-no limit for the stack size limit because those applications can be
-tricked to consume a large portion of the stack and a single glibc call
-could jump over the guard page. These attacks are not theoretical,
-unfortunatelly.
-
-Make those attacks less probable by increasing the stack guard gap
-to 1MB (on systems with 4k pages; but make it depend on the page size
-because systems with larger base pages might cap stack allocations in
-the PAGE_SIZE units) which should cover larger alloca() and VLA stack
-allocations. It is obviously not a full fix because the problem is
-somehow inherent, but it should reduce attack space a lot.
-
-One could argue that the gap size should be configurable from userspace,
-but that can be done later when somebody finds that the new 1MB is wrong
-for some special case applications. For now, add a kernel command line
-option (stack_guard_gap) to specify the stack gap size (in page units).
-
-Implementation wise, first delete all the old code for stack guard page:
-because although we could get away with accounting one extra page in a
-stack vma, accounting a larger gap can break userspace - case in point,
-a program run with "ulimit -S -v 20000" failed when the 1MB gap was
-counted for RLIMIT_AS; similar problems could come with RLIMIT_MLOCK
-and strict non-overcommit mode.
-
-Instead of keeping gap inside the stack vma, maintain the stack guard
-gap as a gap between vmas: using vm_start_gap() in place of vm_start
-(or vm_end_gap() in place of vm_end if VM_GROWSUP) in just those few
-places which need to respect the gap - mainly arch_get_unmapped_area(),
-and and the vma tree's subtree_gap support for that.

-
-commit bd726c90b6b8ce87602208701b208a208e6d5600 upstream.
-
-Fix expand_upwards() on architectures with an upward-growing stack (parisc,
-metag and partly IA-64) to allow the stack to reliably grow exactly up to
-the address space limit given by TASK_SIZE.

-Subject: [PATCH 3/3] mm: fix new crash in unmapped_area_topdown()
-
-commit f4cb767d76cf7ee72f97dd76f6cfa6c76a5edc89 upstream.
-
-Trinity gets kernel BUG at mm/mmap.c:1963! in about 3 minutes of
-mmap testing. That's the VM_BUG_ON(gap_end < gap_start) at the
-end of unmapped_area_topdown(). Linus points out how MAP_FIXED
-(which does not have to respect our stack guard gap intentions)
-could result in gap_end below gap_start there. Fix that, and
-the similar case in its alternative, unmapped_area().
-
-Fixes: 1be7107fbe18 ("mm: larger stack guard gap, between vmas")

-Subject: [PATCH 1/4] Smack: File receive for sockets
-
-The existing file receive hook checks for access on
-the file inode even for UDS. This is not right, as
-the inode is not used by Smack to make access checks
-for sockets. This change checks for an appropriate
-access relationship between the receiving (current)
-process and the socket. If the process can't write
-to the socket's send label or the socket's receive
-label can't write to the process fail.
-
-This will allow the legitimate cases, where the
-socket sender and socket receiver can freely communicate.
-Only strangly set socket labels should cause a problem.

-Subject: [PATCH 3/4] Smack: ignore null signal in smack_task_kill
-
-Kill with signal number 0 is commonly used for checking PID existence.
-Smack treated such cases like any other kills, although no signal is
-actually delivered when sig == 0.
-
-Checking permissions when sig == 0 didn't prevent an unprivileged caller
-from learning whether PID exists or not. When it existed, kernel returned
-EPERM, when it didn't - ESRCH. The only effect of policy check in such
-case is noise in audit logs.
-
-This change lets Smack silently ignore kill() invocations with sig == 0.

-Subject: [PATCH] Allow using obexd without systemd in the user session
-
-Not all sessions run systemd --user (actually, the majority
-doesn't), so the dbus daemon must be able to spawn obexd
-directly, and to do so it needs the full path of the daemon.
-
-Upstream-Status: Denied
-
-Not accepted by upstream maintainer for being a distro specific
-configuration. See thread:

-Subject: [PATCH] Makefile.obexd: add missing mkdir in builtin.h generation
-
-In parallel out-of-tree builds it's possible that obexd/src/builtin.h is
-generated before the target directory has been implicitly created. Solve this by
-creating the directory before writing into it.
