The LFS\n experience suggests not lying and returning an error code might be\n better, but the historical precedent with uids is different and I\n can not think of anything that would break by lying about a uid we\n can\u0027t map.\n\n - Capabilities are localized to the current user namespace making it\n safe to give the initial user in a user namespace all capabilities.\n\n My git tree covers all of the modifications needed to convert the core\n kernel and enough changes to make a system bootable to runlevel 1.\"\n\nFix up trivial conflicts due to nearby independent changes in fs/stat.c\n\n* \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: (46 commits)\n userns: Silence silly gcc warning.\n cred: use correct cred accessor with regards to rcu read lock\n userns: Convert the move_pages, and migrate_pages permission checks to use uid_eq\n userns: Convert cgroup permission checks to use uid_eq\n userns: Convert tmpfs to use kuid and kgid where appropriate\n userns: Convert sysfs to use kgid/kuid where appropriate\n userns: Convert sysctl permission checks to use kuid and kgids.\n userns: Convert proc to use kuid/kgid where appropriate\n userns: Convert ext4 to user kuid/kgid where appropriate\n userns: Convert ext3 to use kuid/kgid where appropriate\n userns: Convert ext2 to use kuid/kgid where appropriate.\n userns: Convert devpts to use kuid/kgid where appropriate\n userns: Convert binary formats to use kuid/kgid where appropriate\n userns: Add negative depends on entries to avoid building code that is userns unsafe\n userns: signal remove unnecessary map_cred_ns\n userns: Teach inode_capable to understand inodes whose uids map to other namespaces.\n userns: Fail exec for suid and sgid binaries with ids outside our user namespace.\n userns: Convert stat to return values mapped from kuids and kgids\n userns: Convert user specfied uids and gids in chown into kuids and kgid\n userns: Use uid_eq gid_eq helpers when comparing kuids and kgids in the vfs\n ...\n" }, { "commit": "ec0d7f18ab7b5097d7c0c8f3d909ca1031b9d5cd", "tree": "7d62c924592145f819ecaa5d60460a05a10dfdbd", "parents": [ "269af9a1a08d368b46d72e74126564d04c354f7e", "1dcc8d7ba235a316a056f993e88f0d18b92c60d9" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed May 23 10:59:07 2012 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed May 23 10:59:07 2012 -0700" }, "message": "Merge branch \u0027x86-fpu-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip\n\nPull fpu state cleanups from Ingo Molnar:\n \"This tree streamlines further aspects of FPU handling by eliminating\n the prepare_to_copy() complication and moving that logic to\n arch_dup_task_struct().\n\n It also fixes the FPU dumps in threaded core dumps, removes and old\n (and now invalid) assumption plus micro-optimizes the exit path by\n avoiding an FPU save for dead tasks.\"\n\nFixed up trivial add-add conflict in arch/sh/kernel/process.c that came\nin because we now do the FPU handling in arch_dup_task_struct() rather\nthan the legacy (and now gone) prepare_to_copy().\n\n* \u0027x86-fpu-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:\n x86, fpu: drop the fpu state during thread exit\n x86, xsave: remove thread_has_fpu() bug check in __sanitize_i387_state()\n coredump: ensure the fpu state is flushed for proper multi-threaded core dump\n fork: move the real prepare_to_copy() users to arch_dup_task_struct()\n" }, { "commit": "02456169e03bcfcebd3115b2a54c1c4a6829c875", "tree": "db7bffbce1e62e4b8d2d9fd3e0d4d2da2b508c0a", "parents": [ "a34157031536c7961106e9787b4548f21b6d7891" ], "author": { "name": "Hendrik Brueckner", "email": "brueckner@linux.vnet.ibm.com", "time": "Wed May 09 16:27:40 2012 +0200" }, "committer": { "name": "Martin Schwidefsky", "email": "schwidefsky@de.ibm.com", "time": "Wed May 23 17:06:52 2012 +0200" }, "message": "s390/irq: split irq stats for cpu-measurement alert facilities\n\nCPU-measurement alerts are generated for different CPU-measurement\nfacilities, for example, the sampling and counter facilities.\nSplit the irq stats according to available facilities.\n\nSigned-off-by: Hendrik Brueckner \u003cbrueckner@linux.vnet.ibm.com\u003e\nSigned-off-by: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\n" }, { "commit": "a34157031536c7961106e9787b4548f21b6d7891", "tree": "e029c374fb57338c9f7be3f39db3baf27f6393e8", "parents": [ "fa7c0043425624ed65b94a6fabe750c7b0af8719" ], "author": { "name": "Michael Holzheu", "email": "holzheu@linux.vnet.ibm.com", "time": "Mon May 21 18:11:29 2012 +0200" }, "committer": { "name": "Martin Schwidefsky", "email": "schwidefsky@de.ibm.com", "time": "Wed May 23 17:06:52 2012 +0200" }, "message": "s390/kexec: Move early_pgm_check_handler() to text section\n\nThe early_pgm_check_handler() function is also used after the\ninit phase in s390_reset_system().

This means\nthat the CPU prefix pages are swapped. The prefix swap for real memory\nworks as follows:\n\nEach CPU owns a prefix register that points to a page aligned memory\nlocation \"P\". If this CPU accesses the address range [0,0x1fff], it is\ntranslated by the hardware to [P,P+0x1fff]. Accordingly if this CPU\naccesses the address range [P,P+0x1fff], it is translated by the hardware\nto [0,0x1fff].

Partially revert\nthe above git commit and go back to s390 specific page table flush code.\n\nFor s390 the TLB can contain three types of entries, \"normal\" TLB\npage-table entries, TLB combined region-and-segment-table (CRST) entries\nand real-space entries. Linux does not use real-space entries which\nleaves normal TLB entries and CRST entries. The CRST entries are\nintermediate steps in the page-table translation called translation paths.\nFor example a 4K page access in a three-level page table setup will\ncreate two CRST TLB entries and one page-table TLB entry. The advantage\nof that approach is that a page access next to the previous one can reuse\nthe CRST entries and needs just a single read from memory to create the\npage-table TLB entry. The disadvantage is that the TLB flushing rules are\nmore complicated, before any page-table may be freed the TLB needs to be\nflushed.\n\nIn short: the generic RCU page-table freeing code is incorrect for the\nCRST entries, in particular the check for mm_users \u003c 2 is troublesome.\n\nThis is applicable to 3.0+ kernels.\n\nCc: \u003cstable@vger.kernel.org\u003e\nSigned-off-by: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\n" }, { "commit": "b785e0d06ac551f80204742682be3218158234d1", "tree": "e0128220a97d1e7478c5ae695062ecd18b3a738b", "parents": [ "dae1df42f544ce3969d437dfa835169210593240" ], "author": { "name": "Michael Holzheu", "email": "holzheu@linux.vnet.ibm.com", "time": "Wed Apr 11 14:28:06 2012 +0200" }, "committer": { "name": "Martin Schwidefsky", "email": "schwidefsky@de.ibm.com", "time": "Wed Apr 11 14:28:24 2012 +0200" }, "message": "[S390] kernel: Use local_irq_save() for memcpy_real()\n\nCurrently in the memcpy_real() function interrupts are disabled with\n__arch_local_irq_stnsm().

asm/system.h into a set of\n separate bits to relieve the problem of circular inclusion\n dependencies.\n\n I\u0027ve built all the working defconfigs from all the arches that I can\n and made sure that they don\u0027t break.\n\n The reason for these patches is that I recently encountered a circular\n dependency problem that came about when I produced some patches to\n optimise get_order() by rewriting it to use ilog2().\n\n This uses bitops - and on the SH arch asm/bitops.h drags in\n asm-generic/get_order.h by a circuituous route involving asm/system.h.\n\n The main difficulty seems to be asm/system.h. It holds a number of\n low level bits with no/few dependencies that are commonly used (eg.\n memory barriers) and a number of bits with more dependencies that\n aren\u0027t used in many places (eg. switch_to()).\n\n These patches break asm/system.h up into the following core pieces:\n\n (1) asm/barrier.h\n\n Move memory barriers here. This already done for MIPS and Alpha.\n\n (2) asm/switch_to.h\n\n Move switch_to() and related stuff here.\n\n (3) asm/exec.h\n\n Move arch_align_stack() here. Other process execution related bits\n could perhaps go here from asm/processor.h.\n\n (4) asm/cmpxchg.h\n\n Move xchg() and cmpxchg() here as they\u0027re full word atomic ops and\n frequently used by atomic_xchg() and atomic_cmpxchg().\n\n (5) asm/bug.h\n\n Move die() and related bits.\n\n (6) asm/auxvec.h\n\n Move AT_VECTOR_SIZE_ARCH here.\n\n Other arch headers are created as needed on a per-arch basis.\"\n\nFixed up some conflicts from other header file cleanups and moving code\naround that has happened in the meantime, so David\u0027s testing is somewhat\nweakened by that.
