We have one\nglobal kretprobe lock to serialise the access to these lists. This causes\nonly one kretprobe handler to execute at a time. Hence affects system\nperformance, particularly on SMP systems and when return probe is set on\nlot of functions (like on all systemcalls).\n\nSolution proposed here gives fine-grain locks that performs better on SMP\nsystem compared to present kretprobe implementation.\n\nSolution:\n\n 1) Instead of having one global lock to protect kretprobe instances\n present in kretprobe object and kretprobe hash table. We will have\n two locks, one lock for protecting kretprobe hash table and another\n lock for kretporbe object.\n\n 2) We hold lock present in kretprobe object while we modify kretprobe\n instance in kretprobe object and we hold per-hash-list lock while\n modifying kretprobe instances present in that hash list. To prevent\n deadlock, we never grab a per-hash-list lock while holding a kretprobe\n lock.\n\n 3) We can remove used_instances from struct kretprobe, as we can\n track used instances of kretprobe instances using kretprobe hash\n table.\n\nTime duration for kernel compilation (\"make -j 8\") on a 8-way ppc64 system\nwith return probes set on all systemcalls looks like this.\n\ncacheline non-cacheline Un-patched kernel\naligned patch \t aligned patch\n\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\nreal 9m46.784s 9m54.412s 10m2.450s\nuser 40m5.715s 40m7.142s 40m4.273s\nsys 2m57.754s 2m58.583s 3m17.430s\n\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\n\nTime duration for kernel compilation (\"make -j 8) on the same system, when\nkernel is not probed.\n\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\nreal 9m26.389s\nuser 40m8.775s\nsys 2m7.283s\n\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\n\nSigned-off-by: Srinivasa DS \u003csrinivasa@in.ibm.com\u003e\nSigned-off-by: Jim Keniston \u003cjkenisto@us.ibm.com\u003e\nAcked-by: Ananth N Mavinakayanahalli \u003cananth@in.ibm.com\u003e\nCc: Anil S Keshavamurthy \u003canil.s.keshavamurthy@intel.com\u003e\nCc: David S.

It adds a new syscall\npaccept. This syscall differs from accept in that it adds (at the userlevel)\ntwo additional parameters:\n\n- a signal mask\n- a flags value\n\nThe flags parameter can be used to set flag like SOCK_CLOEXEC. This is\nimlpemented here as well. Some people argued that this is a property which\nshould be inherited from the file desriptor for the server but this is against\nPOSIX. Additionally, we really want the signal mask parameter as well\n(similar to pselect, ppoll, etc). So an interface change in inevitable.\n\nThe flag value is the same as for socket and socketpair. I think diverging\nhere will only create confusion. Similar to the filesystem interfaces where\nthe use of the O_* constants differs, it is acceptable here.\n\nThe signal mask is handled as for pselect etc. The mask is temporarily\ninstalled for the thread and removed before the call returns. I modeled the\ncode after pselect. If there is a problem it\u0027s likely also in pselect.\n\nFor architectures which use socketcall I maintained this interface instead of\nadding a system call.

This guarantees that a process that successfully calls\nmmap() will successfully fault all pages in the future unless fork() is\ncalled.\n\nThe characteristics of private mappings of hugetlbfs files behaviour after\nthis patch are;\n\n1. The process calling mmap() is guaranteed to succeed all future faults until\n it forks().\n2. On fork(), the parent may die due to SIGKILL on writes to the private\n mapping if enough pages are not available for the COW.

address is in a module\n\nThis patch keeps track of the boundaries of module allocation, in\norder to speed up module_text_address().\n\nInspired by Arjan\u0027s version, which required arch-specific defines:\n\n\tVarious pieces of the kernel (lockdep, latencytop, etc) tend\n\tto store backtraces, sometimes at a relatively high\n\tfrequency. In itself this isn\u0027t a big performance deal (after\n\tall you\u0027re using diagnostics features), but there have been\n\tsome complaints from people who have over 100 modules loaded\n\tthat this is a tad too slow.\n\n\tThis is due to the new backtracer code which looks at every\n\tslot on the stack to see if it\u0027s a kernel/module text address,\n\tso that\u0027s 1024 slots. 1024 times 100 modules... that\u0027s a lot\n\tof list walking.\n\nSigned-off-by: Rusty Russell \u003crusty@rustcorp.com.au\u003e\n" }, { "commit": "2f0f2a334bc38b61a9afca951185cd3844ee709d", "tree": "c73089563f51c818ed97dec463408d6ac9cf1e8e", "parents": [ "f7f5b67557eac1131ba6532522e3c50eced34238" ], "author": { "name": "Denys Vlasenko", "email": "vda.linux@googlemail.com", "time": "Tue Jul 22 19:24:27 2008 -0500" }, "committer": { "name": "Rusty Russell", "email": "rusty@rustcorp.com.au", "time": "Tue Jul 22 19:24:27 2008 +1000" }, "message": "module: turn longs into ints for module sizes\n\nThis shrinks module.o and each *.ko file.\n\nAnd finally, structure members which hold length of module\ncode (four such members there) and count of symbols\nare converted from longs to ints.\n\nWe cannot possibly have a module where 32 bits won\u0027t\nbe enough to hold such counts.\n\nFor one, module loading checks module size for sanity\nbefore loading, so such insanely big module will fail\nthat test first.\n\nSigned-off-by: Denys Vlasenko \u003cvda.linux@googlemail.com\u003e\nSigned-off-by: Rusty Russell \u003crusty@rustcorp.com.au\u003e\n" }, { "commit": "f7f5b67557eac1131ba6532522e3c50eced34238", "tree": "8547b900f4bc40f69673c78b261ac5b44423fbfb", "parents": [ "af5406895a05720a879dc33e2f4878fa503e81b3" ], "author": { "name": "Denys Vlasenko", "email": "vda.linux@googlemail.com", "time": "Tue Jul 22 19:24:26 2008 -0500" }, "committer": { "name": "Rusty Russell", "email": "rusty@rustcorp.com.au", "time": "Tue Jul 22 19:24:27 2008 +1000" }, "message": "Shrink struct module: CONFIG_UNUSED_SYMBOLS ifdefs\n\nmodule.c and module.h conatains code for finding\nexported symbols which are declared with EXPORT_UNUSED_SYMBOL,\nand this code is compiled in even if CONFIG_UNUSED_SYMBOLS is not set\nand thus there can be no EXPORT_UNUSED_SYMBOLs in modules anyway\n(because EXPORT_UNUSED_SYMBOL(x) are compiled out to nothing then).\n\nThis patch adds required #ifdefs.\n\nSigned-off-by: Denys Vlasenko \u003cvda.linux@googlemail.com\u003e\nSigned-off-by: Rusty Russell \u003crusty@rustcorp.com.au\u003e\n" }, { "commit": "dafd0940c96fec67974a88ed8e6b8ba3160394cd", "tree": "616da8f0f283509ec71ff2d6e467fa4c6877edc6", "parents": [ "da39ba5e1d65e997a98f6eb93ba6e6eb505f6e3c" ], "author": { "name": "Rusty Russell", "email": "rusty@rustcorp.com.au", "time": "Tue Jul 22 19:24:25 2008 -0500" }, "committer": { "name": "Rusty Russell", "email": "rusty@rustcorp.com.au", "time": "Tue Jul 22 19:24:26 2008 +1000" }, "message": "module: generic each_symbol iterator function\n\nIntroduce an each_symbol() iterator to avoid duplicating the knowledge\nabout the 5 different sections containing symbols.

The cpumask_of_cpu_map\n is provided when there is a large NR_CPUS count, reducing\n greatly the amount of code generated and stack space used for\n cpumask_of_cpu().
