==================== Changes in man-pages-3.50 ====================
New and rewritten pages -----------------------
canonicalize_file_name.3 Michael Kerrisk Rewrite page, adding much more detail
Changes to individual pages ---------------------------
fork.2 Michael Kerrisk Port access permission bits (ioperm()) are turned off in the child
ioperm.2 Michael Kerrisk Note that iopl() level of 3 is needed to access ports Michael Kerrisk 'num' is *bits* not bytes! Michael Kerrisk Linux 2.6.8 lifted the port limit to 65,536 See http://article.gmane.org/gmane.linux.kernel/202624/ From: Stas Sergeev <stsp <at> aknet.ru> Subject: [patch][rfc] Larger IO bitmap Date: 2004-05-07 19:55:03 GMT Michael Kerrisk ioperm() operates on the calling *thread* (not process) Michael Kerrisk Clarify meaning of 'turn_on' argument Plus form formatting fixes. Michael Kerrisk Clarify that default state of permission bits in child is off Michael Kerrisk NOTES: add mention of /proc/ioports Michael Kerrisk SEE ALSO: add outb(2)
iopl.2 Michael Kerrisk CAP_SYS_RAWIO is required to *raise* the I/O privilege level Michael Kerrisk Clarify that the two least significant bits of 'level' are what matter Michael Kerrisk SEE ALSO: add outb(2)
syscalls.2 Michael Kerrisk Add version information for all (other) syscalls Michael Kerrisk Add perfmonctl(2)
random.4 Elie De Brauwer Document write and document the ioctl interface of /dev/random The update consists out of two parts: - a minor thing which just documents what happens if a write to /dev/(u)random is performed, which is used in the example script but not explicitly mentioned. - the other (biggest) part is the documentation of the ioctl() interface which /dev/(u)random exposes. This ioctl() lives in drivers/char/random.c and the primitives can be found in include/linux/random.h
One comment remains, there used to be an RNDGETPOOL ioctl() which disappeared in v2.6.9. I found two patches on the net: - http://www.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.8.1/2.6.8.1-mm4/broken-out/dev-random-remove-rndgetpool-ioctl.patch - https://lkml.org/lkml/2004/3/25/168
But as far as I can tell the first one got applied but the 2nd one seems more correct. The result is that even today one can still find traces of the RNDGETPOOL ioctl() in the header files. Is this there for historical reasons or because it might break userspace, even though using it will just give an EINVAL.
bootparam.7 Jose Luis Domingo Lopez Document 'rootfstype' option See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=182014
capabilities.7 Michael Kerrisk Add various pieces under CAP_SYS_RAWIO Info obtained by grepping the kernel source. Michael Kerrisk Add CAP_SYS_RESOURCE /proc/PID/oom_score_adj case
netlink.7 Andrey Vagin Add a note about broadcast messages to multiple groups
