2013-02-09kconfig: nconf: rewrite help textsRoland Eggner1-164/+156
>From: Roland Eggner <edvx1@systemanalysen.net> Rewrite all help texts. During several years lazy (incomplete) updates have left behind a rather thick layer of dust. Intentions: (1) Global help called by <F1> should document all _currently_ implemented keybindings. (2) Different help texts called by <F3> resp. <F8><F1> should be consistent with (1) and with implementation: • on plain menu entry • in radiolist window • in input windows for text, decimal or hexadecimal values • in filename selection windows <F6> <F7> • SymSearch specific help called by <F8> followed by <F1> (3) More reasonable window titles: Rename window title s/README/Global help/ Rename variable s/nconf_readme/nconf_global_help/ Rename window title s/Instructions/Short help/ (4) Consider which hints are most useful for first-time-users.

2012-11-20kconfig: get CONFIG_ prefix from the environmentYann E. MORIN3-2/+3
Currently, the CONFIG_ prefix is hard-coded in the kconfig frontends executables. This means that two projects that use kconfig with different prefixes can not share the same kconfig frontends.

2012-11-20kconfig: add a function to get the CONFIG_ prefixYann E. MORIN1-0/+6
Currently, we get the CONFIG_ prefix via the CONFIG_ macro, which means the CONFIG_ prefix is hard-coded at compile time. This goes against having a run-time defined CONFIG_ prefix. Add a function that returns the CONFIG_ prefix to use (but keep the current hard-coded behavior, to be changed in a later patch). To avoid touching all the code that uses the CONFIG_ macro, we just undef it, and define it to be a call to the function. Signed-off-by: "Yann E.

2012-11-20menuconfig: fix extended colors ncurses supportKrzysztof Mazur1-0/+1
The ncurses library allows for extended colors. The support for extended colors support depends on wide-character support. ncurses headers enable extended colors (NCURSES_EXT_COLORS) only when wide-character support is enabled (NCURSES_WIDECHAR). The "make menuconfig" uses wide-character ncursesw library, which can be compiled with wide-character support, but does not define NCURSES_WIDECHAR and it's using headers without wide-character (and extended colors) support. This fixes problems with colors on systems with enabled extended colors (like PLD Linux). Without this patch "make menuconfig" is hard to use.

2012-10-14x86, boot: Explicitly include autoconf.h for hostprogsMatt Fleming1-1/+2
The hostprogs need access to the CONFIG_* symbols found in include/generated/autoconf.h. But commit abbf1590de22 ("UAPI: Partition the header include path sets and add uapi/ header directories") replaced $(LINUXINCLUDE) with $(USERINCLUDE) which doesn't contain the necessary include paths. This has the undesirable effect of breaking the EFI boot stub because the #ifdef CONFIG_EFI_STUB code in arch/x86/boot/tools/build.c is never compiled. It should also be noted that because $(USERINCLUDE) isn't exported by the top-level Makefile it's actually empty in arch/x86/boot/Makefile. Cc: H.

2012-10-13ARM: config: sort select statements alphanumericallyRussell King39-767/+765
As suggested by Andrew Morton: This is a pet peeve of mine. Any time there's a long list of items (header file inclusions, kconfig entries, array initalisers, etc) and someone wants to add a new item, they *always* go and stick it at the end of the list. Guys, don't do this. Either put the new item into a randomly-chosen position or, probably better, alphanumerically sort the list. lets sort all our select statements alphanumerically. This commit was created by the following perl: while (<>) { while (/\\\s*$/) { $_ .= <>; } undef %selects if /^\s*config\s+/; if (/^\s+select\s+(\w+).*/) { if (defined($selects{$1})) { if ($selects{$1} eq $_) { print STDERR "Warning: removing duplicated $1 entry\n"; } else { print STDERR "Error: $1 differently selected\n". "\tOld: $selects{$1}\n". "\tNew: $_\n"; exit 1; } } $selects{$1} = $_; next; } if (%selects and (/^\s*$/ or /^\s+help/ or /^\s+---help---/ or /^endif/ or /^endchoice/)) { foreach $k (sort (keys %selects)) { print "$selects{$k}"; } undef %selects; } print; } if (%selects) { foreach $k (sort (keys %selects)) { print "$selects{$k}"; } } It found two duplicates: Warning: removing duplicated S5P_SETUP_MIPIPHY entry Warning: removing duplicated HARDIRQS_SW_RESEND entry and they are identical duplicates, hence the shrinkage in the diffstat of two lines.

2012-10-12vfs: define struct filename and have getname() return itJeff Layton40-175/+218
getname() is intended to copy pathname strings from userspace into a kernel buffer. The result is just a string in kernel space. It would however be quite helpful to be able to attach some ancillary info to the string. For instance, we could attach some audit-related info to reduce the amount of audit-related processing needed. When auditing is enabled, we could also call getname() on the string more than once and not need to recopy it from userspace. This patchset converts the getname()/putname() interfaces to return a struct instead of a string. For now, the struct just tracks the string in kernel space and the original userland pointer for it. Later, we'll add other information to the struct as it becomes convenient. Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2012-10-12dm: store dm_target_io in bio front_padMikulas Patocka1-59/+49
Use the recently-added bio front_pad field to allocate struct dm_target_io. Prior to this patch, dm_target_io was allocated from a mempool. For each dm_target_io, there is exactly one bio allocated from a bioset. This patch merges these two allocations into one allocation: we create a bioset with front_pad equal to the size of dm_target_io so that every bio allocated from the bioset has sizeof(struct dm_target_io) bytes before it. We allocate a bio and use the bytes before the bio as dm_target_io. _tio_cache is removed and the tio_pool mempool is now only used for request-based devices.

This patch eliminates the "Discard support must be disabled when the block size is not a power of 2" constraint that was imposed in commit 55f2b8b ("dm thin: support for non power of 2 pool blocksize").

2012-10-12tcp: resets are misroutedAlexey Kuznetsov2-4/+6
After commit e2446eaa ("tcp_v4_send_reset: binding oif to iif in no sock case").. tcp resets are always lost, when routing is asymmetric. Yes, backing out that patch will result in misrouting of resets for dead connections which used interface binding when were alive, but we actually cannot do anything here. What's died that's died and correct handling normal unbound connections is obviously a priority. Comment to comment: > This has few benefits: > 1. tcp_v6_send_reset already did that. It was done to route resets for IPv6 link local addresses. It was a mistake to do so for global addresses. The patch fixes this as well. Actually, the problem appears to be even more serious than guaranteed loss of resets. As reported by Sergey Soloviev <sol@eqv.ru>, those misrouted resets create a lot of arp traffic and huge amount of unresolved arp entires putting down to knees NAT firewalls which use asymmetric routing.
