Instead it affects the children\ncreated with fork and clone. The first of these children becomes the init\nprocess of the new pid namespace, the rest become oddball children\nof pid 0. From the point of view of the new pid namespace the process\nthat created it is pid 0, as it\u0027s pid does not map.\n\nA couple of different semantics were considered but this one was\nsettled on because it is easy to implement and it is usable from\npam modules. The core reasons for the existence of unshare.\n\nI took a survey of the callers of pam modules and the following\nappears to be a representative sample of their logic.\n{\n\tsetup stuff include pam\n\tchild \u003d fork();\n\tif (!child) {\n\t\tsetuid()\n exec /bin/bash\n }\n waitpid(child);\n\n pam and other cleanup\n}\n\nAs you can see there is a fork to create the unprivileged user\nspace process. Which means that the unprivileged user space\nprocess will appear as pid 1 in the new pid namespace. Further\nmost login processes do not cope with extraneous children which\nmeans shifting the duty of reaping extraneous child process to\nthe creator of those extraneous children makes the system more\ncomprehensible.\n\nThe practical reason for this set of pid namespace semantics is\nthat it is simple to implement and verify they work correctly.\nWhereas an implementation that requres changing the struct\npid on a process comes with a lot more races and pain. Not\nthe least of which is that glibc caches getpid().\n\nThese semantics are implemented by having two notions\nof the pid namespace of a proces. There is task_active_pid_ns\nwhich is the pid namspace the process was created with\nand the pid namespace that all pids are presented to\nthat process in. The task_active_pid_ns is stored\nin the struct pid of the task.\n\nThen there is the pid namespace that will be used for children\nthat pid namespace is stored in task-\u003ensproxy-\u003epid_ns.\n\nSigned-off-by: Eric W.

Both bitmap_set from\nlib/bitmap.c and bitmap_set_ll, which is the lockless version from\ngenalloc.c, use BITMAP_LAST_WORD_MASK to set the first bits in a long in\nthe bitmap.\n\nThat one uses (1 \u003c\u003c bits) - 1, 0b111, if you are setting the first three\nbits. This means that the API counts from the least significant bits\n(LSB from now on) to the MSB. The LSB in the first long is bit 0, then.\nThe same works for the lookup functions.\n\nThe genalloc code uses longs for the bitmap, as it should. In\ninclude/linux/genalloc.h, struct gen_pool_chunk has unsigned long\nbits[0] as its last member. When allocating the struct, genalloc should\nreserve enough space for the bitmap. This should be a proper number of\nlongs that can fit the amount of bits in the bitmap.\n\nHowever, genalloc allocates an integer number of bytes that fit the\namount of bits, but may not be an integer amount of longs. 9 bytes, for\nexample, could be allocated for 70 bits.\n\nThis is a problem in itself if the Least Significat Bit in a long is in\nthe byte with the largest address, which happens in Big Endian machines.\nThis means genalloc is not allocating the byte in which it will try to\nset or check for a bit.\n\nThis may end up in memory corruption, where genalloc will try to set the\nbits it has not allocated. In fact, genalloc may not set these bits\nbecause it may find them already set, because they were not zeroed since\nthey were not allocated. And that\u0027s what causes a BUG when\ngen_pool_destroy is called and check for any set bits.\n\nWhat really happens is that genalloc uses kmalloc_node with __GFP_ZERO\non gen_pool_add_virt. With SLAB and SLUB, this means the whole slab\nwill be cleared, not only the requested bytes. Since struct\ngen_pool_chunk has a size that is a multiple of 8, and slab sizes are\nmultiples of 8, we get lucky and allocate and clear the right amount of\nbytes.\n\nHower, this is not the case with SLOB or with older code that did memset\nafter allocating instead of using __GFP_ZERO.\n\nSo, a simple module as this (running 3.6.0), will cause a crash when\nrmmod\u0027ed.\n\n [root@phantom-lp2

Thus when a page is written to via buffered\nwrite, HW dirty bit gets set and when we later map and unmap the page,\npage_remove_rmap() finds the dirty bit and calls set_page_dirty().\n\nDirtying of a page which shouldn\u0027t be dirty can cause all sorts of\nproblems to filesystems. The bug we observed in practice is that\nbuffers from the page get freed, so when the page gets later marked as\ndirty and writeback writes it, XFS crashes due to an assertion\nBUG_ON(!PagePrivate(page)) in page_buffers() called from\nxfs_count_page_state().\n\nSimilar problem can also happen when zero_user_segment() call from\nxfs_vm_writepage() (or block_write_full_page() for that matter) set the\nhardware dirty bit during writeback, later buffers get freed, and then\npage unmapped.\n\nFix the issue by ignoring s390 HW dirty bit for page cache pages of\nmappings with mapping_cap_account_dirty(). This is safe because for\nsuch mappings when a page gets marked as writeable in PTE it is also\nmarked dirty in do_wp_page() or do_page_fault(). When the dirty bit is\ncleared by clear_page_dirty_for_io(), the page gets writeprotected in\npage_mkclean().
