Worse, any subsequent .fixup code gets intermingled with\nthe code its supposed to be fixing (which is also in .fixup). It\u0027s\nsurprising this didn\u0027t cause more havok.\n\nThe fix is to use .pushsection/.popsection, so this stuff nests\nproperly. A further cleanup would be to get rid of all\n.section/.previous pairs, since they\u0027re inherently fragile.\n\n+From: Chuck Ebbert \u003c76306.1226@compuserve.com\u003e\n\nBecause code marked unsafe for kprobes jumps directly to\nentry.S::error_code, that must be marked unsafe as well.\nThe easiest way to do that is to move the page fault entry\npoint to just before error_code and let it inherit the same\nsection.\n\nAlso moved all the \".previous\" asm directives for kprobes\nsections to column 1 and removed \".text\" from them.\n\nSigned-off-by: Chuck Ebbert \u003c76306.1226@compuserve.com\u003e\nSigned-off-by: Andi Kleen \u003cak@suse.de\u003e\n" }, { "commit": "62c4f0a2d5a188f73a94f2cb8ea0dba3e7cf0a7f", "tree": "e85ca2d0dd43f90dccf758338764c3caa55f333f", "parents": [ "089f26d5e31b7bf42a9a8fefec08b30cd27f4b0e" ], "author": { "name": "David Woodhouse", "email": "dwmw2@infradead.org", "time": "Wed Apr 26 12:56:16 2006 +0100" }, "committer": { "name": "David Woodhouse", "email": "dwmw2@infradead.org", "time": "Wed Apr 26 12:56:16 2006 +0100" }, "message": "Don\u0027t include linux/config.h from anywhere else in include/\n\nSigned-off-by: David Woodhouse \u003cdwmw2@infradead.org\u003e\n" }, { "commit": "ab7efcc97ebc92e03c0474dfd38f9c7b84b84115", "tree": "b0eb6b9abce5c47af9c61b606f37ec1c4d247e65", "parents": [ "09fe316a7b10219be592118626850e1dfdfcc1aa" ], "author": { "name": "Jan Beulich", "email": "jbeulich@novell.com", "time": "Fri Mar 24 03:16:17 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Mar 24 07:33:25 2006 -0800" }, "message": "[PATCH] abstract type/size specification for assembly\n\nProvide abstraction for generating type and size information of assembly\nroutines and data, while permitting architectures to override these\ndefaults.\n\nSigned-off-by: Jan Beulich \u003cjbeulich@novell.com\u003e\nCc: \"Russell King\" \u003crmk@arm.linux.org.uk\u003e\nCc: Ralf Baechle \u003cralf@linux-mips.org\u003e\nCc: \"Andi Kleen\" \u003cak@suse.de\u003e\nCc: \"Luck, Tony\" \u003ctony.luck@intel.com\u003e\nCc: Miles Bader \u003cuclinux-v850@lsi.nec.co.jp\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "d0aaff9796c3310326d10da44fc0faed352a1d29", "tree": "591fd8dedf34464989d23bbb0e66a1ccb2fa18a6", "parents": [ "505db03639db34ca2c64fe7ee27190d324281f2c" ], "author": { "name": "Prasanna S Panchamukhi", "email": "prasanna@in.ibm.com", "time": "Tue Sep 06 15:19:26 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Sep 07 16:57:59 2005 -0700" }, "message": "[PATCH] Kprobes: prevent possible race conditions generic\n\nThere are possible race conditions if probes are placed on routines within the\nkprobes files and routines used by the kprobes. For example if you put probe\non get_kprobe() routines, the system can hang while inserting probes on any\nroutine such as do_fork(). Because while inserting probes on do_fork(),\nregister_kprobes() routine grabs the kprobes spin lock and executes\nget_kprobe() routine and to handle probe of get_kprobe(), kprobes_handler()\ngets executed and tries to grab kprobes spin lock, and spins forever. This\npatch avoids such possible race conditions by preventing probes on routines\nwithin the kprobes file and routines used by kprobes.\n\nI have modified the patches as per Andi Kleen\u0027s suggestion to move kprobes\nroutines and other routines used by kprobes to a seperate section\n.kprobes.text.\n\nAlso moved page fault and exception handlers, general protection fault to\n.kprobes.text section.\n\nThese patches have been tested on i386, x86_64 and ppc64 architectures, also\ncompiled on ia64 and sparc64 architectures.\n\nSigned-off-by: Prasanna S Panchamukhi \u003cprasanna@in.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "1da177e4c3f41524e886b7f1b8a0c1fc7321cac2", "tree": "0bba044c4ce775e45a88a51686b5d9f90697ea9d", "parents": [], "author": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sat Apr 16 15:20:36 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sat Apr 16 15:20:36 2005 -0700" }, "message": "Linux-2.6.12-rc2\n\nInitial git repository build.
