      "message": "ppc64 sys_ipc breakage in 2.6.34-rc2\n\nI chased down a fail on ppc64 on 2.6.34-rc2 where an application that\nuses shared memory was getting a SEGV.\n\nCommit baed7fc9b580bd3fb8252ff1d9b36eaf1f86b670 (\"Add generic sys_ipc\nwrapper\") changed the second argument from an unsigned long to an int.\nWhen we call shmget the system call wrappers for sys_ipc will sign\nextend second (ie the size) which truncates it.  It took a while to\ntrack down because the call succeeds and strace shows the untruncated\nsize :)\n\nThe patch below changes second from an int to an unsigned long which\nfixes shmget on ppc64 (and I assume s390, sparc64 and mips64).\n\nSigned-off-by: Anton Blanchard \u003canton@samba.org\u003e\n--\n\nI assume the function prototypes for the other IPC methods would cause us\nto sign or zero extend second where appropriate (avoiding any security\nissues). Come to think of it, the syscall wrappers for each method should do\nthat for us as well.\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "Add generic sys_ipc wrapper\n\nAdd a generic implementation of the ipc demultiplexer syscall.  Except for\ns390 and sparc64 all implementations of the sys_ipc are nearly identical.\n\nThere are slight differences in the types of the parameters, where mips\nand powerpc as the only 64-bit architectures with sys_ipc use unsigned\nlong for the \"third\" argument as it gets casted to a pointer later, while\nit traditionally is an \"int\" like most other paramters.  frv goes even\nfurther and uses unsigned long for all parameters execept for \"ptr\" which\nis a pointer type everywhere.  The change from int to unsigned long for\n\"third\" and back to \"int\" for the others on frv should be fine due to the\nin-register calling conventions for syscalls (we already had a similar\nissue with the generic sys_ptrace), but I\u0027d prefer to have the arch\nmaintainers looks over this in details.\n\nExcept for that h8300, m68k and m68knommu lack an impplementation of the\nsemtimedop sub call which this patch adds, and various architectures have\ngets used - at least on i386 it seems superflous as the compat code on\nx86-64 and ia64 doesn\u0027t even bother to implement it.\n\n[akpm@linux-foundation.org: add sys_ipc to sys_ni.c]\nSigned-off-by: Christoph Hellwig \u003chch@lst.de\u003e\nCc: Ralf Baechle \u003cralf@linux-mips.org\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nCc: Paul Mundt \u003clethal@linux-sh.org\u003e\nCc: Jeff Dike \u003cjdike@addtoit.com\u003e\nCc: Hirokazu Takata \u003ctakata@linux-m32r.org\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nReviewed-by: H.
