So, it blocked off some signals, including SIGUSR1, on entry to the\nSIGSEGV handler, queued a SIGUSR1 to itself, and invoked sigreturn. The\nSIGUSR1 was delivered, and was visible to the UML kernel after sigreturn\nfinished.\n\nThe commit eliminated the signal masking and the call to sigreturn. The\nhandler simply hits itself with a SIGTRAP to let the UML kernel know that it\nis finished. UML then restores the process registers, which effectively\nlongjmps the process out of the signal handler, skipping sigreturn\u0027s restoring\nof register state and the signal mask.\n\nThe bug is that the host apparently sets used_fp to 0 when it saves the\nprocess FP state in the sigcontext on the process signal stack. Thus, when\nthe process is longjmped out of the handler, its FP state is corrupt because\nit wasn\u0027t saved on the context switch to the UML kernel.\n\nThis manifested itself as sleep hanging. For some reason, sleep uses floating\npoint in order to calculate the sleep interval. When a page fault corrupts\nits FP state, it is faked into essentially sleeping forever.\n\nThis patch saves the FP state before entering the SIGSEGV handler and restores\nit afterwards.\n\nSigned-off-by: Jeff Dike \u003cjdike@linux.intel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "ac2a659968f5318a180213f0409c2ea21f072820", "tree": "2bebff50071f9f9fef802d2434de951e9c235332", "parents": [ "5aaf5f7b871abf00fb2525e7ed2d5938a74ce23c" ], "author": { "name": "Jeff Dike", "email": "jdike@addtoit.com", "time": "Fri Feb 08 04:22:11 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Fri Feb 08 09:22:43 2008 -0800" }, "message": "uml: fix mm_context memory leak\n\n[ Spotted by Miklos ]\n\nFix a memory leak in init_new_context.

This allows the removal of a truly nasty kludge to make\nsure that mm-\u003enr_ptes was correct in exit_mmap. The underlying problem was\nalways that the stubs, which have ptes, and thus allocated a page table,\nweren\u0027t covered by a VMA.\n\nThis patch fixes that by using install_special_mapping in arch_dup_mmap and\nactivate_context to create the VMA. The stubs have to be moved, since\nshift_arg_pages seems to assume that the stack is the only VMA present at that\npoint during exec, and uses vma_adjust to fiddle its VMA. However, that\nextends the stub VMA by the amount removed from the stack VMA.\n\nTo avoid this problem, the stubs were moved to a different fixed location at\nthe start of the address space.\n\nThe init_stub_pte calls were moved from init_new_context to arch_dup_mmap\nbecause I was occasionally seeing arch_dup_mmap not being called, causing\nexit_mmap to die. Rather than figure out what was really happening, I decided\nit was cleaner to just move the calls so that there\u0027s no doubt that both the\npte and VMA creation happen, no matter what. arch_exit_mmap is used to clear\nthe stub ptes at exit time.\n\nThe STUB_* constants in as-layout.h no longer depend on UM_TASK_SIZE, that\nthat definition is removed, along with the comments complaining about gcc.\n\nBecause the stubs are no longer at the top of the address space, some care is\nneeded while flushing TLBs. update_pte_range checks for addresses in the stub\nrange and skips them. flush_thread now issues two unmaps, one for the range\nbefore STUB_START and one for the range after STUB_END.\n\nSigned-off-by: Jeff Dike \u003cjdike@linux.intel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "42a2b54ce8c7b9d4f418995a7950e7e2e15e52ce", "tree": "30bcb0ea0a4ee6d5091b1b9a85589cff8b1863fc", "parents": [ "b7c000cbc4f1fa7b82efa95b34f00c2adbeaa3fe" ], "author": { "name": "Jeff Dike", "email": "jdike@addtoit.com", "time": "Mon Feb 04 22:31:00 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue Feb 05 09:44:29 2008 -0800" }, "message": "uml: clean up TASK_SIZE usage\n\nClean up the calculation and use of the usable address space size on the host.\n\ntask_size is gone, replaced with TASK_SIZE, which is calculated from\nCONFIG_TOP_ADDR. get_kmem_end and set_task_sizes_skas are also gone.\n\nhost_task_size, which refers to the entire address space usable by the UML\nkernel and which may be larger than the address space usable by a UML process,\nsince that has to end on a pgdir boundary, is replaced by CONFIG_TOP_ADDR.\n\nSTACK_TOP is now TASK_SIZE minus the two stub pages.\n\nSigned-off-by: Jeff Dike \u003cjdike@linux.intel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "3e6f2ac480ce398ade2fd6b5e02d00d1265f1e0f", "tree": "25f5589189170c20a765d4e6f0c56b42ad58ea20", "parents": [ "d25f2e1235aab716c9fd6ba36c42503627a3a0e3" ], "author": { "name": "Jeff Dike", "email": "jdike@addtoit.com", "time": "Mon Feb 04 22:30:58 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue Feb 05 09:44:28 2008 -0800" }, "message": "uml: kill processes instead of panicing kernel\n\nUML was panicing in the case of failures of libc calls which shouldn\u0027t happen.\n This is an overreaction since a failure from libc doesn\u0027t normally mean that\nkernel data structures are in an unknown state. Instead, the current process\nshould just be killed if there is no way to recover.\n\nThe case that prompted this was a failure of PTRACE_SETREGS restoring the same\nstate that was read by PTRACE_GETREGS. It appears that when a process tries\nto load a bogus value into a segment register, it segfaults (as expected) and\nthe value is actually loaded and is seen by PTRACE_GETREGS (not expected).\n\nThis case is fixed by forcing a fatal SIGSEGV on the process so that it\nimmediately dies. fatal_sigsegv was added for this purpose. It was declared\nas noreturn, so in order to pursuade gcc that it actually does not return, I\nadded a call to os_dump_core (and declared it noreturn) so that I get a core\nfile if somehow the process survives.\n\nAll other calls in arch/um/os-Linux/skas/process.c got the same treatment,\nwith failures causing the process to die instead of a kernel panic, with some\nexceptions.\n\nuserspace_tramp exits with status 1 if anything goes wrong there. That will\ncause start_userspace to return an error. copy_context_skas0 and\nmap_stub_pages also now return errors instead of panicing.
