On the FRV arch, removing the regs parameter\nfrom all the genirq function results in a 20% speed up of the IRQ exit path\n(ie: from leaving timer_interrupt() to leaving do_IRQ()).\n\nWhere appropriate, an arch may override the generic storage facility and do\nsomething different with the variable. On FRV, for instance, the address is\nmaintained in GR28 at all times inside the kernel as part of general exception\nhandling.\n\nHaving looked over the code, it appears that the parameter may be handed down\nthrough up to twenty or so layers of functions. Consider a USB character\ndevice attached to a USB hub, attached to a USB controller that posts its\ninterrupts through a cascaded auxiliary interrupt controller. A character\ndevice driver may want to pass regs to the sysrq handler through the input\nlayer which adds another few layers of parameter passing.\n\nI\u0027ve build this code with allyesconfig for x86_64 and i386. I\u0027ve runtested the\nmain part of the code on FRV and i386, though I can\u0027t test most of the drivers.\nI\u0027ve also done partial conversion for powerpc and MIPS - these at least compile\nwith minimal configurations.\n\nThis will affect all archs. Mostly the changes should be relatively easy.\nTake do_IRQ(), store the regs pointer at the beginning, saving the old one:\n\n\tstruct pt_regs *old_regs \u003d set_irq_regs(regs);\n\nAnd put the old one back at the end:\n\n\tset_irq_regs(old_regs);\n\nDon\u0027t pass regs through to generic_handle_irq() or __do_IRQ().\n\nIn timer_interrupt(), this sort of change will be necessary:\n\n\t-\tupdate_process_times(user_mode(regs));\n\t-\tprofile_tick(CPU_PROFILING, regs);\n\t+\tupdate_process_times(user_mode(get_irq_regs()));\n\t+\tprofile_tick(CPU_PROFILING);\n\nI\u0027d like to move update_process_times()\u0027s use of get_irq_regs() into itself,\nexcept that i386, alone of the archs, uses something other than user_mode().\n\nSome notes on the interrupt handling in the drivers:\n\n (*) input_dev() is now gone entirely. The regs pointer is no longer stored in\n the input_dev struct.\n\n (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does\n something different depending on whether it\u0027s been supplied with a regs\n pointer or not.\n\n (*) Various IRQ handler function pointers have been moved to type\n irq_handler_t.\n\nSigned-Off-By: David Howells \u003cdhowells@redhat.com\u003e\n(cherry picked from 1b16e7ac850969f38b375e511e3fa2f474a33867 commit)\n" }, { "commit": "1a657f78dcc8ea7c53eaa1f2a45ea2315738c15f", "tree": "a19972027792082fed505c8d540f7d877e37c0ab", "parents": [ "1c0d04c9e44f4a248335c33d2be7c7f7b06ff359" ], "author": { "name": "Oleg Nesterov", "email": "oleg@tv-sign.ru", "time": "Mon Oct 02 02:18:59 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Mon Oct 02 07:57:25 2006 -0700" }, "message": "[PATCH] introduce get_task_pid() to fix unsafe get_pid()\n\nproc_pid_make_inode:\n\n\tei-\u003epid \u003d get_pid(task_pid(task));\n\nI think this is not safe. get_pid() can be preempted after checking \"pid\n!\u003d NULL\".

For this race to trigger the process that proc_pid_readdir stops at\nmust exit before readdir is called again.\n\nThis can cause ps to fail to report processes, and it is in violation of\nposix guarantees and normal application expectations with respect to\nreaddir.\n\nCurrently there is no way to work around this problem in user space short\nof providing a gargantuan buffer to user space so the directory read all\nhappens in on system call.\n\nThis patch implements the normal directory semantics for proc, that\nguarantee that a directory entry that is neither created nor destroyed\nwhile reading the directory entry will be returned. For directory that are\neither created or destroyed during the readdir you may or may not see them.\n Furthermore you may seek to a directory offset you have previously seen.\n\nThese are the guarantee that ext[23] provides and that posix requires, and\nmore importantly that user space expects. Plus it is a simple semantic to\nimplement reliable service. It is just a matter of calling readdir a\nsecond time if you are wondering if something new has show up.\n\nThese better semantics are implemented by scanning through the pids in\nnumerical order and by making the file offset a pid plus a fixed offset.\n\nThe pid scan happens on the pid bitmap, which when you look at it is\nremarkably efficient for a brute force algorithm. Given that a typical\ncache line is 64 bytes and thus covers space for 64*8 \u003d\u003d 200 pids. There\nare only 40 cache lines for the entire 32K pid space. A typical system\nwill have 100 pids or more so this is actually fewer cache lines we have to\nlook at to scan a linked list, and the worst case of having to scan the\nentire pid bitmap is pretty reasonable.\n\nIf we need something more efficient we can go to a more efficient data\nstructure for indexing the pids, but for now what we have should be\nsufficient.\n\nIn addition this takes no additional locks and is actually less code than\nwhat we are doing now.\n\nAlso another very subtle bug in this area has been fixed. It is possible\nto catch a task in the middle of de_thread where a thread is assuming the\nthread of it\u0027s thread group leader.

This does not prohibit NFS roots or JFFS2.\n\n (*) The bdflush, ioprio_set and ioprio_get syscalls can now be absent (return\n error ENOSYS by way of cond_syscall if so).\n\n (*) The seclvl_bd_claim() and seclvl_bd_release() security calls do nothing if\n CONFIG_BLOCK is not set, since they can\u0027t then happen.\n\nSigned-Off-By: David Howells \u003cdhowells@redhat.com\u003e\nSigned-off-by: Jens Axboe \u003caxboe@kernel.dk\u003e\n" }, { "commit": "632dd2053a1146c826ceb6f26ab689389c05e751", "tree": "439c457364f5b58e2de09950e5e0854968e3cde2", "parents": [ "327dcaadc0bc08ad081aa8e36b6ec7ad7aa45e30" ], "author": { "name": "Vivek Goyal", "email": "vgoyal@in.ibm.com", "time": "Fri Sep 29 02:01:45 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Sep 29 09:18:25 2006 -0700" }, "message": "[PATCH] Kcore elf note namesz field fix\n\no As per ELF specifications, it looks like that elf note \"namesz\" field\n contains the length of \"name\" including the size of null character.

The chroot check was\nasking a question about the visibility of files to the calling process and\nit was actually checking the destination process, and not the files\nthemselves. That test was clearly bogus.\n\nIn my first pass through I simply fixed the test to check the visibility of\nthe files themselves. That naive approach to fixing the permissions was\ntoo strict and resulted in cases where a task could not even see all of\nit\u0027s file descriptors.\n\nWhat has disturbed me about relaxing this check is that file descriptors\nare per-process private things, and they are occasionaly used a user space\ncapability tokens. Looking a little farther into the symlink path on /proc\nI did find userid checks and a check for capability (CAP_DAC_OVERRIDE) so\nthere were permissions checking this.\n\nBut I was still concerned about privacy. Besides /proc there is only one\nother way to find out this kind of information, and that is ptrace. ptrace\nhas been around for a long time and it has a well established security\nmodel.\n\nSo after thinking about it I finally realized that the permission checks\nthat make sense are the permission checks applied to ptrace_attach. The\nchecks are simple per process, and won\u0027t cause nasty surprises for people\ncoming from less capable unices.\n\nUnfortunately there is one case that the current ptrace_attach test does\nnot cover: Zombies and kernel threads. Single stepping those kinds of\nprocesses is impossible. Being able to see which file descriptors are open\non these tasks is important to lsof, fuser and friends. So for these\nspecial processes I made the rule you can\u0027t find out unless you have\nCAP_SYS_PTRACE.\n\nThese proc permission checks should now conform to the principle of least\nsurprise.
