He also\nsuggested using system call instead of /proc/\u003cpid\u003e/ interface, I decided to\nuse the latter continuously because adding new system call with pid argument\nwill give a big impact on the kernel.\n\nYou can access the per-process flags via /proc/\u003cpid\u003e/coredump_filter\ninterface. coredump_filter represents a bitmask of memory types, and if a bit\nis set, VMAs of corresponding memory type are written into a core file when\nthe process is dumped. The bitmask is inherited from the parent process when\na process is created.\n\nThe original purpose is to avoid longtime system slowdown when a number of\nprocesses which share a huge shared memory are dumped at the same time. To\nachieve this purpose, this patch series adds an ability to suppress dumping\nanonymous shared memory for specified processes. In this version, three other\nmemory types are also supported.\n\nHere are the coredump_filter bits:\n bit 0: anonymous private memory\n bit 1: anonymous shared memory\n bit 2: file-backed private memory\n bit 3: file-backed shared memory\n\nThe default value of coredump_filter is 0x3. This means the new core dump\nroutine has the same behavior as conventional behavior by default.\n\nIn this version, coredump_filter bits and mm.dumpable are merged into\nmm.flags, and it is accessed by atomic bitops.\n\nThe supported core file formats are ELF and ELF-FDPIC. ELF has been tested,\nbut ELF-FDPIC has not been built and tested because I don\u0027t have the test\nenvironment.\n\nThis patch limits a value of suid_dumpable sysctl to the range of 0 to 2.\n\nSigned-off-by: Hidehiro Kawai \u003chidehiro.kawai.ez@hitachi.com\u003e\nCc: Alan Cox \u003calan@lxorguk.ukuu.org.uk\u003e\nCc: David Howells \u003cdhowells@redhat.com\u003e\nCc: Hugh Dickins \u003chugh@veritas.com\u003e\nCc: Nick Piggin \u003cnickpiggin@yahoo.com.au\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "b6a2fea39318e43fee84fa7b0b90d68bed92d2ba", "tree": "c9c3619cb2730b5c10c7427b837146bce3d69156", "parents": [ "bdf4c48af20a3b0f01671799ace345e3d49576da" ], "author": { "name": "Ollie Wild", "email": "aaw@google.com", "time": "Thu Jul 19 01:48:16 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Thu Jul 19 10:04:45 2007 -0700" }, "message": "mm: variable length argument support\n\nRemove the arg+env limit of MAX_ARG_PAGES by copying the strings directly from\nthe old mm into the new mm.\n\nWe create the new mm before the binfmt code runs, and place the new stack at\nthe very top of the address space.

Namely, in that cases we need\nto disable the GPEs before replacing the \"boot\" kernel with the \"frozen\"\nkernel (cf. http://bugzilla.kernel.org/show_bug.cgi?id\u003d7887). After the\nrestore they will be re-enabled by hibernation_ops-\u003efinish(), but if the\nrestore fails, they have to be re-enabled by the restore code explicitly.\n\nFor this purpose we can introduce two additional hibernation operations,\ncalled pre_restore() and restore_cleanup() and call them from the restore code\npath. Still, they should be called if the \"platform\" mode of hibernation has\nbeen used, so we need to pass the information about the hibernation mode from\nthe \"frozen\" kernel to the \"boot\" kernel in the image header.\n\nApparently, we can\u0027t drop the disabling of GPEs before the restore because of\nBug #7887 .  We also can\u0027t do it unconditionally, because the GPEs wouldn\u0027t\nhave been enabled after a successful restore if the suspend had been done in\nthe \u0027shutdown\u0027 or \u0027reboot\u0027 mode.\n\nIn principle we could (and probably should) unconditionally disable the GPEs\nbefore each snapshot creation *and* before the restore, but then we\u0027d have to\nunconditionally enable them after the snapshot creation as well as after the\nrestore (or restore failure)   Still, for this purpose we\u0027d need to modify\nacpi_enter_sleep_state_prep() and acpi_leave_sleep_state() and we\u0027d have to\nintroduce some mechanism synchronizing the disablind/enabling of the GPEs with\nthe device drivers\u0027 .suspend()/.resume() routines and with\ndisable_/enable_nonboot_cpus().  However, this would have affected the\nsuspend (ie. s2ram) code as well as the hibernation, which I\u0027d like to avoid\nin this patch series.\n\nSigned-off-by: Rafael J.

This is\nrequired by various security standards such as DCID 6/3 and PCI to provide\nnon-repudiation of administrator\u0027s actions and to allow a review of past\nactions if the administrator seems to overstep their duties or if the system\nbecomes misconfigured for unknown reasons. These requirements do not make it\nnecessary to audit TTY output as well.\n\nCompared to an user-space keylogger, this approach records TTY input using the\naudit subsystem, correlated with other audit events, and it is completely\ntransparent to the user-space application (e.g. the console ioctls still\nwork).\n\nTTY input auditing works on a higher level than auditing all system calls\nwithin the session, which would produce an overwhelming amount of mostly\nuseless audit events.\n\nAdd an \"audit_tty\" attribute, inherited across fork (). Data read from TTYs\nby process with the attribute is sent to the audit subsystem by the kernel.\nThe audit netlink interface is extended to allow modifying the audit_tty\nattribute, and to allow sending explanatory audit events from user-space (for\nexample, a shell might send an event containing the final command, after the\ninteractive command-line editing and history expansion is performed, which\nmight be difficult to decipher from the TTY input alone).\n\nBecause the \"audit_tty\" attribute is inherited across fork (), it would be set\ne.g. for sshd restarted within an audited session. To prevent this, the\naudit_tty attribute is cleared when a process with no open TTY file\ndescriptors (e.g. after daemon startup) opens a TTY.\n\nSee https://www.redhat.com/archives/linux-audit/2007-June/msg00000.html for a\nmore detailed rationale document for an older version of this patch.\n\n[akpm@linux-foundation.org: build fix]\nSigned-off-by: Miloslav Trmac \u003cmitr@redhat.com\u003e\nCc: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nCc: Alan Cox \u003calan@lxorguk.ukuu.org.uk\u003e\nCc: Paul Fulghum \u003cpaulkf@microgate.com\u003e\nCc: Casey Schaufler \u003ccasey@schaufler-ca.com\u003e\nCc: Steve Grubb \u003csgrubb@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "4f27c00bf80f122513d3a5be16ed851573164534", "tree": "2abad49c1e5c93d2d8698c558eb490b99bd35b87", "parents": [ "f3dc8c189a20dc5d115b8f0d07ac620e69eff05c" ], "author": { "name": "Alan Cox", "email": "alan@lxorguk.ukuu.org.uk", "time": "Sun Jul 15 23:40:55 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Mon Jul 16 09:05:46 2007 -0700" }, "message": "Improve behaviour of spurious IRQ detect\n\nCurrently we handle spurious IRQ activity based upon seeing a lot of\ninvalid interrupts, and we clear things back on the base of lots of valid\ninterrupts.\n\nUnfortunately in some cases you get legitimate invalid interrupts caused by\ntiming asynchronicity between the PCI bus and the APIC bus when disabling\ninterrupts and pulling other tricks.
