We had reports of several races, including\nsome reports of apps bypassing our recursion check so that a process that\nwas forked as part of a core_pattern setup could infinitely crash and\nrefork until the system crashed.\n\nWe fixed those by improving our recursion checks. The new check basically\nrefuses to fork a process if its core limit is zero, which works well.\n\nUnfortunately, I\u0027ve been getting grief from maintainer of user space\nprograms that are inserted as the forked process of core_pattern. They\ncontend that in order for their programs (such as abrt and apport) to\nwork, all the running processes in a system must have their core limits\nset to a non-zero value, to which I say \u0027yes\u0027. I did this by design, and\nthink thats the right way to do things.\n\nBut I\u0027ve been asked to ease this burden on user space enough times that I\nthought I would take a look at it. The first suggestion was to make the\nrecursion check fail on a non-zero \u0027special\u0027 number, like one. That way\nthe core collector process could set its core size ulimit to 1, and enable\nthe kernel\u0027s recursion detection. This isn\u0027t a bad idea on the surface,\nbut I don\u0027t like it since its opt-in, in that if a program like abrt or\napport has a bug and fails to set such a core limit, we\u0027re left with a\nrecursively crashing system again.\n\nSo I\u0027ve come up with this. What I\u0027ve done is modify the\ncall_usermodehelper api such that an extra parameter is added, a function\npointer which will be called by the user helper task, after it forks, but\nbefore it exec\u0027s the required process. This will give the caller the\nopportunity to get a call back in the processes context, allowing it to do\nwhatever it needs to to the process in the kernel prior to exec-ing the\nuser space code. In the case of do_coredump, this callback is ues to set\nthe core ulimit of the helper process to 1. This elimnates the opt-in\nproblem that I had above, as it allows the ulimit for core sizes to be set\nto the value of 1, which is what the recursion check looks for in\ndo_coredump.\n\nThis patch:\n\nCreate new function call_usermodehelper_fns() and allow it to assign both\nan init and cleanup function, as we\u0027ll as arbitrary data.\n\nThe init function is called from the context of the forked process and\nallows for customization of the helper process prior to calling exec. Its\nreturn code gates the continuation of the process, or causes its exit.\nAlso add an arbitrary data pointer to the subprocess_info struct allowing\nfor data to be passed from the caller to the new process, and the\nsubsequent cleanup process\n\nAlso, use this patch to cleanup the cleanup function. It currently takes\nan argp and envp pointer for freeing, which is ugly. Lets instead just\nmake the subprocess_info structure public, and pass that to the cleanup\nand init routines\n\nSigned-off-by: Neil Horman \u003cnhorman@tuxdriver.com\u003e\nReviewed-by: Oleg Nesterov \u003coleg@redhat.com\u003e\nCc: Andi Kleen \u003candi@firstfloor.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "065add3941bdca54fe04ed3471a96bce9af88793", "tree": "0c3505a04bb1b54926c527644c0ee2f57680c250", "parents": [ "e0129ef91ed758c06b6557c36124acfb2e1c7305" ], "author": { "name": "Oleg Nesterov", "email": "oleg@redhat.com", "time": "Wed May 26 14:42:54 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu May 27 09:12:44 2010 -0700" }, "message": "signals: check_kill_permission(): don\u0027t check creds if same_thread_group()\n\nAndrew Tridgell reports that aio_read(SIGEV_SIGNAL) can fail if the\nnotification from the helper thread races with setresuid(), see\nhttp://samba.org/~tridge/junkcode/aio_uid.c\n\nThis happens because check_kill_permission() doesn\u0027t permit sending a\nsignal to the task with the different cred-\u003exids.

So we should catch it.\n\nBTW, historically, above implemntation comes from migration-failure\nof anonymous page. Because we charge both of old page and new page\nwith mapcount\u003d0, we can\u0027t catch\n - the page is really freed before remap.\n - migration fails but it\u0027s freed before remap\nor .....corner cases.\n\nNew migration sequence with memcg is:\n\n 1. allocate a new page.\n 2. mark PageCgroupMigration to the old page.\n 3. charge against a new page onto the old page\u0027s memcg. (here, new page\u0027s pc\n is marked as PageCgroupUsed.)\n 4. page migration replaces radix-tree, page table, etc...\n 5. At remapping, new page\u0027s page_cgroup is now makrked as \"USED\"\n We can catch 0-\u003e1 event and FILE_MAPPED will be properly updated.\n\n And we can catch SWAPOUT event after unlock this and freeing this\n page by unmap() can be caught.\n\n 7. Clear PageCgroupMigration of the old page.\n\nSo, FILE_MAPPED will be correctly updated.\n\nThen, for what MIGRATION flag is ?\n Without it, at migration failure, we may have to charge old page again\n because it may be fully unmapped. \"charge\" means that we have to dive into\n memory reclaim or something complated. So, it\u0027s better to avoid\n charge it again. Before this patch, __commit_charge() was working for\n both of the old/new page and fixed up all. But this technique has some\n racy condtion around FILE_MAPPED and SWAPOUT etc...\n Now, the kernel use MIGRATION flag and don\u0027t uncharge old page until\n the end of migration.\n\nI hope this change will make memcg\u0027s page migration much simpler.
