70839a950bcee0684fe8435afcece612e92a5382 - i386 removal, part 71/x: Remove legacy FreeBSD brand.

Thu, 14 Mar 2019 21:11:33 +0000

i386 removal, part 71/x: Remove legacy FreeBSD brand.We had a compat layer in i386 that was intended to run old DragonFlybinaries from <1.2 times if my memory serves well. That also workedwith FreeBSD 4.x binaries. It was removed in part 7 and 8 of thiscommit series.This commit reverts cee191cabfed209fdad9972bd88be5b18e310361.It also removes all references to ld-elf.so.1.Reported-by: zrj List of files: /dflybsd-src/libexec/rtld-elf/Makefile

Sat, 28 Apr 2018 05:30:03 +0000

calloc - Work around gcc-8 bug (2).GCC-8 at -O2 improperly tries to optimize calloc() replacement even formalloc+bzero sequence back to calloc from calloc itself. This affectsboth main root's shell (tcsh as default) and ld-elf.so dynamic linker.Explicitly use -fno-builtin-malloc to prevent that at any -Ox level.

Dynamic root: Move ld-elf.so.2 to /libexec* Install it first to avoid breaking upgrades for systems previously having it located in /usr/libexec. install(1), beeing a dynamic binary, needs it at runtime.* Since ld-elf.so.2's path is embedded in ELF binaries, also create a symbolic link in the old location to support existing binaries.* Code to handle chflags attributes obtained from FreeBSD.

Thu, 13 Jun 2013 07:19:29 +0000

rtld: Sync 7/7 - Use symbol versioning instead of exports mappingNow that DragonFly has the symbol versioning framework in place, rtldcan leverage it by offloading the symbol export duties to it. Thisfurther reduces differences between FreeBSD and DragonFly linkers.Keeping the exports table up to date after FreeBSD removed it was extrawork.

7f5c8f9721216c496b54eff209b96f6f5f6bd189 - rtld: Add main object initialization and finalization

Sat, 17 Mar 2012 18:52:17 +0000

rtld: Add main object initialization and finalizationSince DragonFly's inception, crt1 has called _init and _fini functions ofthe binary rather than leaving this task to the runtime linker. Likelythis was done in order to use the same crt code for both statically anddynamically linked binaries.When FreeBSD imported DragonFly's preinit, init, and fini array handlingcode, they moved the _init and _fini calls to rtld. In order for rtld tomaintain compatiblity with binaries created with crt code that call thesefunctions, rtld looks for an ELF note that indicates the binary was builtwith a crt that does not call _init and _fini.This commit imports this capability as well as synchronizes some of thechanges FreeBSD made to the DragonFly code. Many of the differencesweren't necessary, but some represented improvements. In any case, itbenefits both operating systems to minimize the differences between theruntime linkers in order to continue to collaborate and share newfeatures.Taken from: FreeBSD SVN 232831 (2012-03-11)One key difference between the DragonFly and FreeBSD implementations isthat FreeBSD will not properly execute a binary that requiresinitialization and/or finalization if the PT_NOTE program header isintentionally omitted using a custom linker script and the PHDRSdirective. In the same case, DragonFly will look to see if the mainbinary contains a gnu hash dynamic tag. If it does, it assumes the binarywas built with the new crt, which is a very good assumption. Since gnuhash was inserted by default into binaries only a week ago, there's onlya window of few days where this isn't true, and PT_NOTE-free binaries arevery rare.

abfcd5b1045e58aecb0f84d4e269d0d1b3b20d6e - rtld: Make thread-safe by replacing libc printf functions

Sat, 21 Jan 2012 15:07:30 +0000

rtld: Make thread-safe by replacing libc printf functionsThe dynamic linker is linked with the specially built static pic libc toget some C runtime services such as printf(). Unfortunately, themultithread-safeness measures in libc do now work in the rtld environment.The dynlinker now uses FreeBSD's kernel printf() implementation instead oflibc's version. This printf does not require any shared global data andthus is mt-safe. This commit replaces printf() and related functions withrtld_ versions, and also removes calls to err(3).Currently stdio is still pulled from libc within the libmap implementationthat uses fopen(). This is safe, yet not optimal, and is a candidate forfuture change.The makefile was cleaned up to remove the unused bits to building anexecutable dynlinker and also require gnu99.Taken-from: FreeBSD SVN 225152 List of files: /dflybsd-src/libexec/rtld-elf/Makefile

a1eee96a9ec31b34bf52c63e2eeffb68f7904b18 - Major TLS cleanups.

Wed, 11 May 2005 19:47:09 +0000

Major TLS cleanups.* The RTLD no longer attempts to set up an initial TLS. The job has been moved to libc. The RTLD does not use TLS itself. The allocate_initial_tls() function has been removed.* The _init_tls() call made by CRT1 is no mandatory.* The RTLD no longer calls the library _init() functions early. Instead it sets up a callback that allows CRT1 to call the library _init() functions after it has called _init_tls().* LIBC now has a _libc_init_tls() function which is weakly bound as _init_tls(). This function initializes the TLS for the program (generally by calling the _rtld_allocate_tls() and then doing any required post-allocation initialization). In the absence of a threading library this function is basically it. Threading libraries may replace _init_tls() with their own version. This does not yet occur as of this commit. The threading library would then almost certainly call _libc_init_tls() and then make further modifications to the TCB as necessary (e.g. populate the tcb_pthread field).* RTLD's allocate_tls() no longer does anything fancy. The 'old_tcb' argument and concept has been removed.* We have a new tcb_errno_p field in the TCB, but as of this commit it is not yet being used.Reviewed-by: Joerg Sonnenberger , David Xu List of files: /dflybsd-src/libexec/rtld-elf/Makefile

Make a special libc version for RTLD which doesn't use TLS as it willsoon be added. Don't install it, keep it in the build tree. Alsobuild the rtld itself without TLS dependencies.
