Fixing that is hard, while SYSEMU is easier to implement.\n\n* This version of the patch includes some suggestions of Jeff Dike to avoid\n adding any instructions to the syscall fast path, plus some other little\n changes, by myself, to make it work even when the syscall is executed with\n SYSENTER (but I\u0027m unsure about them). It has been widely tested for quite a\n lot of time.\n\n* Various fixed were included to handle the various switches between\n various states, i.e. when for instance a syscall entry is traced with one of\n PT_SYSCALL / _SYSEMU / _SINGLESTEP and another one is used on exit.\n Basically, this is done by remembering which one of them was used even after\n the call to ptrace_notify().\n\n* We\u0027re combining TIF_SYSCALL_EMU with TIF_SYSCALL_TRACE or TIF_SINGLESTEP\n to make do_syscall_trace() notice that the current syscall was started with\n SYSEMU on entry, so that no notification ought to be done in the exit path;\n this is a bit of a hack, so this problem is solved in another way in next\n patches.\n\n* Also, the effects of the patch:\n\"Ptrace - i386: fix Syscall Audit interaction with singlestep\"\nare cancelled; they are restored back in the last patch of this series.\n\nDetailed descriptions of the patches doing this kind of processing follow (but\nI\u0027ve already summed everything up).\n\n* Fix behaviour when changing interception kind #1.\n\n In do_syscall_trace(), we check the status of the TIF_SYSCALL_EMU flag\n only after doing the debugger notification; but the debugger might have\n changed the status of this flag because he continued execution with\n PTRACE_SYSCALL, so this is wrong. This patch fixes it by saving the flag\n status before calling ptrace_notify().\n\n* Fix behaviour when changing interception kind #2:\n avoid intercepting syscall on return when using SYSCALL again.\n\n A guest process switching from using PTRACE_SYSEMU to PTRACE_SYSCALL\n crashes.\n\n The problem is in arch/i386/kernel/entry.S. The current SYSEMU patch\n inhibits the syscall-handler to be called, but does not prevent\n do_syscall_trace() to be called after this for syscall completion\n interception.\n\n The appended patch fixes this. It reuses the flag TIF_SYSCALL_EMU to\n remember \"we come from PTRACE_SYSEMU and now are in PTRACE_SYSCALL\", since\n the flag is unused in the depicted situation.\n\n* Fix behaviour when changing interception kind #3:\n avoid intercepting syscall on return when using SINGLESTEP.\n\n When testing 2.6.9 and the skas3.v6 patch, with my latest patch and had\n problems with singlestepping on UML in SKAS with SYSEMU. It looped\n receiving SIGTRAPs without moving forward. EIP of the traced process was\n the same for all SIGTRAPs.\n\nWhat\u0027s missing is to handle switching from PTRACE_SYSCALL_EMU to\nPTRACE_SINGLESTEP in a way very similar to what is done for the change from\nPTRACE_SYSCALL_EMU to PTRACE_SYSCALL_TRACE.\n\nI.e., after calling ptrace(PTRACE_SYSEMU), on the return path, the debugger is\nnotified and then wake ups the process; the syscall is executed (or skipped,\nwhen do_syscall_trace() returns 0, i.e. when using PTRACE_SYSEMU), and\ndo_syscall_trace() is called again. Since we are on the return path of a\nSYSEMU\u0027d syscall, if the wake up is performed through ptrace(PTRACE_SYSCALL),\nwe must still avoid notifying the parent of the syscall exit. Now, this\nbehaviour is extended even to resuming with PTRACE_SINGLESTEP.\n\nSigned-off-by: Paolo \u0027Blaisorblade\u0027 Giarrusso \u003cblaisorblade@yahoo.it\u003e\nCc: Jeff Dike \u003cjdike@addtoit.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "94c80b2598dbd2b8a6fe5f5c2c3af1beb37f66c7", "tree": "7e4221c42418898084961f66670c7f66042f164c", "parents": [ "08b178ebf37bbfb78329e0ae6ea688b103d205bf" ], "author": { "name": "Bodo Stroesser", "email": "bstroesser@fujitsu-siemens.com", "time": "Sat Sep 03 15:57:13 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@evo.osdl.org", "time": "Mon Sep 05 00:06:19 2005 -0700" }, "message": "[PATCH] Ptrace/i386: fix \"syscall audit\" interaction with singlestep\n\n Paolo \u0027Blaisorblade\u0027 Giarrusso \u003cblaisorblade@yahoo.it\u003e\n\nAvoid giving two traps for singlestep instead of one, when syscall auditing is\nenabled.\n\nIn fact no singlestep trap is sent on syscall entry, only on syscall exit, as\ncan be seen in entry.S:\n\n# Note that in this mask _TIF_SINGLESTEP is not tested !!! \u003c\u003c\u003c\u003c\u003c\u003c\u003c\u003c\u003c\u003c\u003c\u003c\u003c\u003c\n testb $(_TIF_SYSCALL_TRACE|_TIF_SYSCALL_AUDIT|_TIF_SECCOMP),TI_flags(%ebp)\n jnz syscall_trace_entry\n\t...\nsyscall_trace_entry:\n\t...\n\tcall do_syscall_trace\n\nBut auditing a SINGLESTEP\u0027ed process causes do_syscall_trace to be called, so\nthe tracer will get one more trap on the syscall entry path, which it\nshouldn\u0027t.\n\nSigned-off-by: Paolo \u0027Blaisorblade\u0027 Giarrusso \u003cblaisorblade@yahoo.it\u003e\nCC: Roland McGrath \u003croland@redhat.com\u003e\nCc: Jeff Dike \u003cjdike@addtoit.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "08b178ebf37bbfb78329e0ae6ea688b103d205bf", "tree": "e11c4ac3015681bd60b66c47a1131d221435e916", "parents": [ "96e59245e1abf3ea2e98c4b9ee2ebd975db653db" ], "author": { "name": "Jeff Dike", "email": "jdike@addtoit.com", "time": "Sat Sep 03 15:57:12 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@evo.osdl.org", "time": "Mon Sep 05 00:06:19 2005 -0700" }, "message": "[PATCH] uml: Rename Kconfig files to be like the other arches\n\nTo the extent that sub-Kconfig files exist elsewhere in the tree, they are\nnamed Kconfig.foo, rather than the Kconfig_foo that UML has.

I\u0027ve modified platform check code and\nremoved unnecessary OEM table parsing for newer systems that don\u0027t use OEM\ninformation during boot. Parsing the table in fact is causing problems,\nand the platform doesn\u0027t get recognized. The patch only affects the ES7000\nsubach.\n\nSigned-off-by: \u003cNatalie.Protasevich@unisys.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "252943efcfce945d8dd3738ca4c4b9cbeb4f3fa9", "tree": "c197c27a57e3cb0af818b304373d2b0e8fd6e40b", "parents": [ "911a62d42365076209e2c327e7688db296e35d62" ], "author": { "name": "Venkatesh Pallipadi", "email": "venkatesh.pallipadi@intel.com", "time": "Sat Sep 03 15:56:32 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@evo.osdl.org", "time": "Mon Sep 05 00:06:10 2005 -0700" }, "message": "[PATCH] x86: Add the check for all the cores in a package in cache information\n\nSigned-off-by: Venkatesh Pallipadi \u003cvenkatesh.pallipadi@intel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "911a62d42365076209e2c327e7688db296e35d62", "tree": "51e6d8525cd3547ea43129b5dd20339655674d57", "parents": [ "484b90c4b965d54037ff99b198d84cdf144f8a35" ], "author": { "name": "Venkatesh Pallipadi", "email": "venkatesh.pallipadi@intel.com", "time": "Sat Sep 03 15:56:31 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@evo.osdl.org", "time": "Mon Sep 05 00:06:10 2005 -0700" }, "message": "[PATCH] x86: sutomatically enable bigsmp when we have more than 8 CPUs\n\ni386 generic subarchitecture requires explicit dmi strings or command line\nto enable bigsmp mode.

In kexec on\n panic case parameter segment might well be loaded beyond kernel image and\n might not be addressable by early boot page tables.\no This case might hit in the scenario where user has reserved a chunk of\n memory for second kernel, for example 16MB to 64MB, and has also built\n second kernel for physical memory location 16MB. In this case kexec has no\n choice but to load the parameter segment at a higher address than new kernel\n image at safe location where new kernel does not stomp it.\no Though problem should automatically go away once relocatable kernel for i386\n is in place and kexec can determine the location of new kernel at run time\n and load parameter segment at lower address than kernel image.

Now boot parameters\n are copied out in protected mode before page tables are initialized.
