* Android is all-PIC/PIE.Elliott Hughes2014-08-077-50/+2
| | | | | | | | | | | Clean up the x86/x86_64 assembler. The motivator (other than reducing confusion) was that asm.h incorrectly checked PIC rather than __PIC__. Bug: 16823325 (cherry picked from commit 6b6364a7fc7c3ba37ee907776a29bdc8c9793db9) Change-Id: I89ca57fa0eb34a36de6cb11ea85f71054fce709d

| * Do a second key cleanup in pthread_exit.Christopher Ferris2014-08-061-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | During pthread_exit, the keys are cleaned. Unfortunately, a call to free occurs after the cleanup and the memory for some of the keys is recreated when using jemalloc. The solution is to do the key cleanup twice. Also, modify the pthread_detach__leak test to be less flaky when run on a jemalloc system. Bug: 16513133 Change-Id: Ic17e8344bdc1ba053c4f5b6d827a4c19c57860c1

(Thanks to Alexander Krivenyshev.) There are a few exceptions: Magadan Oblast (Asia/Magadan) and Zabaykalsky Krai are subtracting two hours; conversely, Chukotka Autonomous Okrug (Asia/Anadyr), Kamchatka Krai (Asia/Kamchatka), Kemerovo Oblast (Asia/Novokuznetsk), and the Samara Oblast and the Udmurt Republic (Europe/Samara) are not changing their clocks. The changed zones are Europe/Kaliningrad, Europe/Moscow, Europe/Simferopol, Europe/Volgograd, Asia/Yekaterinburg, Asia/Omsk, Asia/Novosibirsk, Asia/Krasnoyarsk, Asia/Irkutsk, Asia/Yakutsk, Asia/Vladivostok, Asia/Khandyga, Asia/Sakhalin, and Asia/Ust-Nera; Asia/Magadan will have two hours subtracted; and Asia/Novokuznetsk's time zone abbreviation is affected, but not its UTC offset. Two zones are added: Asia/Chita (split from Asia/Yakutsk, and also with two hours subtracted) and Asia/Srednekolymsk (split from Asia/Magadan, but with only one hour subtracted). (Thanks to Tim Parenti for much of the above.) Changes affecting past time stamps China's five zones have been simplified to two, since the post-1970 differences in the other three seem to have been imaginary. The zones Asia/Harbin, Asia/Chongqing, and Asia/Kashgar have been removed; backwards-compatibility links still work, albeit with different behaviors for time stamps before May 1980. Asia/Urumqi's 1980 transition to UTC+8 has been removed, so that it is now at UTC+6 and not UTC+8. (Thanks to Luther Ma and to Alois Treindl; Treindl sent helpful translations of two papers by Guo Qingsheng.) Some zones have been turned into links, when they differed from existing zones only for older UTC offsets where the data were likely invented. These changes affect UTC offsets in pre-1970 time stamps only. This is similar to the change in release 2013e, except this time for western Africa. The affected zones are: Africa/Bamako, Africa/Banjul, Africa/Conakry, Africa/Dakar, Africa/Freetown, Africa/Lome, Africa/Nouakchott, Africa/Ouagadougou, Africa/Sao_Tome, and Atlantic/St_Helena. This also affects the backwards-compatibility link Africa/Timbuktu. (Thanks to Alan Barrett, Stephen Colebourne, Tim Parenti, and David Patte for reporting problems in earlier versions of this change.) Asia/Shanghai's pre-standard-time UT offset has been changed from 8:05:57 to 8:05:43, the location of Xujiahui Observatory. Its transition to standard time has been changed from 1928 to 1901. Asia/Taipei switched to JWST on 1896-01-01, then to JST on 1937-10-01, then to CST on 1945-09-21 at 01:00, and did not observe DST in 1945. In 1946 it observed DST from 05-15 through 09-30; in 1947 from 04-15 through 10-31; and in 1979 from 07-01 through 09-30. (Thanks to Yu-Cheng Chuang.) Asia/Riyadh's transition to standard time is now 1947-03-14, not 1950. Europe/Helsinki's 1942 fall-back transition was 10-04 at 01:00, not 10-03 at 00:00. (Thanks to Konstantin Hyppönen.) Pacific/Pago_Pago has been changed from UTC-11:30 to UTC-11 for the period from 1911 to 1950. Pacific/Chatham has been changed to New Zealand standard time plus 45 minutes for the period before 1957, reflecting a 1956 remark in the New Zealand parliament. Europe/Budapest has several pre-1946 corrections: in 1918 the transition out of DST was on 09-16, not 09-29; in 1919 it was on 11-24, not 09-15; in 1945 it was on 11-01, not 11-03; in 1941 the transition to DST was 04-08 not 04-06 at 02:00; and there was no DST in 1920. Africa/Accra is now assumed to have observed DST from 1920 through 1935. Time in Russia before 1927 or so has been corrected by a few seconds in the following zones: Europe/Moscow, Asia/Irkutsk, Asia/Tbilisi, Asia/Tashkent, Asia/Vladivostok, Asia/Yekaterinburg, Europe/Helsinki, and Europe/Riga. Also, Moscow's location has been changed to its Kilometer 0 point. (Thanks to Vladimir Karpinsky for the Moscow changes.) Bug: 16168653 Change-Id: I23827254bcf50dd07a2192ed34b02224d73e07a0

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The recent libcore ZoneInfo changes mean that we can no longer compile libcore's ZoneInfo against the RI. Luckily, the field in our data file that we needed ZoneInfo for isn't actually used. This change removes our dependence on libcore. I've left the field in to avoid a file format change. We can remove the field if/when we next have a real need to bump the file format. Bug: 16168653 Change-Id: Iedad2252c2b49f4d8bb2c7d9078b39b622444ca7

| | | | | | | | | | | | | | | | | | | | Create a method of disabling the debug allocation code paths so that it's possible to use the libunwindbacktrace library without any modifications. Use this path to create and destroy the maps for the process. It's not stricly necessary in the init code since the symbols are not modified until after the initialize calls. Also, remove the debug_XXX source files that doesn't need to be in libc.so. Fix the maps reading code since it was completely broken for 64 bit.

| | | | | | | | | | | | | It seemed like a clever trick to use the internal log message formatting code in syslog(3), but on reflection that means you can't (for example) format floating point numbers.

There's no obvious way to unit test this, so I wrote a little program and ran that. Bug: 14292866 Change-Id: I9c83500ba9cbb209b6f496067a91bf69434eeef5

* [MIPS] Allow united mipsel and mips64el gcc toolchainDuane Sand2014-07-221-0/+3
| | | | | | | | | | Explicitly tell 32-bit links that they are doing 32-bit links. This is needed when using united 32-bit and 64-bit toolchains. This is harmless when using older separate 32-only toolchains. (cherry picked from commit f541650828f75b3dab22c9c0caab845be78b80fc) Change-Id: I8df0ee7d36c6409458e18bea4e0e8b132edf77dc

* Use upstream OpenBSD's arc4random.Elliott Hughes2014-07-218-291/+915
| | | | | | | | | The getentropy_linux.c is lightly modified to build on Android, but we're now completely in sync with upstream OpenBSD's arc4random implementation. (cherry picked from commit 2b67d7dee09852789d9ac7d8972ed6cdb2c18430) Change-Id: Icc939b5fa2fcac3e15ff93735d2d34f67e9bb149
* Rewrite syslog(3) to use Android logging.Elliott Hughes2014-07-215-406/+90
| | | | | | | | | | | | Since we don't have syslogd on Android and you can't run one on a non-rooted device, it's more useful if syslog output just goes to the regular Android logging system. Bug: 14292866 (cherry picked from commit 3ad8ecb64e9dd5614169232b84a93eb3b8aa32d7) Change-Id: I3038855ca4f22532bf6d2c45d3f8028b866975f9
