When a page fault occurs on an address below the stack-vma, UML tries to expand the stack. On i386 and x86_64, the failing address is compared to the current userspace stack pointer. If the failing address is below "esp-32" resp. "rsp-128", stack expansion is not allowed, and a SIGSEGV is given to the user. This patch makes UML behave like i386/x86_64. Signed-off-by:

This adds code which enables SIGSEGV reception to the SKAS sig_handler_common, which matches the tt code. I still need to figure out why the SA_NODEFER flag was backed out in favor of this. Signed-off-by:

Re-add some needed headers inclusion deleted in http://linux.bkbits.net:8080/linux-2.5/cset@41e49628dGbOWX-bT9yZII4f19GT6A If you think it cannot make sense to include both <sys/ptrace.h> and <linux/ptrace.h> (as userspace process, i.e. host includes), go complaining with glibc, or follow the linux-abi includes idea. However, the compilation failure is possibly glibc-version (or better glibc includes version) related - what I now is that the failure happens on my system with a glibc 2.3.4 (from Gentoo). Also, fix the syscall table to both compile and have no empty slot (which could cause Oopses). Acked-by:

With NFSD=y, EXPORTFS=m: fs/built-in.o(.text+0x7fff5): In function `fh_verify': /usr/src/25/fs/nfsd/nfsfh.c:221: undefined reference to `export_op_default' So it seems that nfsd requires exportfs. For consistency we should tidy up the definition of EXPORTFS too. Signed-off-by:

Fixes the math of both jiffies_to_usecs() and usecs_to_jiffies() which improperly assume the same rounding point -- 1,000 -- as jiffies_to_msecs() and msecs_to_jiffies(), when in fact it should be 1,000,000. Furthermore, the actual math of both functions is actually wrong and will lead to more than just rounding errors. Signed-off-by:

This fixes the selinux_inode_setattr hook function to honor the ATTR_FORCE flag, skipping any permission checking in that case. Otherwise, it is possible though unlikely for a denial from the hook to prevent proper updating, e.g. for remove_suid upon writing to a file. This would only occur if the process had write permission to a suid file but lacked setattr permission to it. Signed-off-by:

This fixes a race in the FRV arch's semaphore implementation. The same type of fixes were applied to the rw-semaphore implementations to fix the same races there. The race involved the on-stack record linked into the semaphore's queue by the down() executed by a process now sleeping on the semaphore going away and the sleeping task going away before the process that woke it up during up() processing had finished with those structures.

From: Steffen Thoss <thoss@de.ibm.com> From: Frank Pavlic <pavlic@de.ibm.com> qeth network driver changes: - Improve performance by omitting svs. - Use function callback mechanism to set layer 2 parameters when getting a reply for a Layer 2 command. - dev->hard_header must not be NULL when fake_ll is no set since IPv6 and Layer2 needs the default function set by network stack. - ping6 works now when running in layer 2 mode. - Save original dev->hard_header to restore it when the user doesn't want to use fake_ll anymore. - Fake ethernet header in outgoing packets. This currently works only if qeth is compiled without ipv6 support. - Add more debug information in case of failures in qeth_set_offline. - Using fake_ll with HiperSockets devices results in misaligned ip packets and thus no traffic over HiperSockets. - Start qeth_remove_device only after the qeth recovery completed.

- Diagnose 8 needs a response buffer below 2GB real storage. As the caller cannot always allocate the buffer with GFP_DMA the best solution is to rewrite cpcmd to use a bounce buffer if necessary. The old function was renamed to __cpcmd and can be called if appropriate. The early boot code does not provide kmalloc but need cpcmd functionality. These places have been converted to use __cpcmd, as the init code and data are below 2GB. - In case of an 31 bit system, cpcmd is defined as __cpcmd. - EXPORT_SYMBOL(cpcmd) moved into cpcmd.c - some whitespace fixes in cpcmd.[c/h] Signed-off-by:
