* btrfs-progs: build: fix building libbtrfs.so with tsanDavid Sterba2017-09-08
| | | | | | | | | | | | Except libbtrfs.so object, all other tools compile fine. The error is: ld: send-stream.o: relocation R_X86_64_PC32 against symbol `stderr@@GLIBC_2.2.5' can not be used when making a shared object; recompile with -fPIC Compiling with -fPIC fixes the problem.

* btrfs-progs: build: properly pass the LDFLAGS during tsan buildDavid Sterba2017-09-08
| | | | | | | The variable LD_FLAGS does not exist and the flags are not used, we need to use the newly added internal debugging linker flags. Signed-off-by: David Sterba <dsterba@suse.com>

* btrfs-progs: convert: add support for converting reiserfsJeff Mahoney2017-09-08
| | | | | | | | | | | | | This patch adds support to convert reiserfs file systems in-place to btrfs. It will convert extended attribute files to btrfs extended attributes, translate ACLs, coalesce tails that consist of multiple items into one item, and convert tails that are too big into indirect files. This requires that libreiserfscore 3.6.27 be available. Signed-off-by: Jeff Mahoney <jeffm@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>
* btrfs-progs: Specify C standard to gnu90 explicitlyQu Wenruo2017-08-24
| | | | | | | | | | | | | | | | | | Different C compilers have different default language standard. This sometimes causes problem on different system. For distribution like CentOS/RHEL7, its gcc is still 4.8 and will report error for c90 style declaration, while most developers are using newer gcc which will just ignore it. This makes us hard to detect such language standard problem. This patch will specify standard to gnu90 explicitly to avoid such problem. Gnu90 is a good mix of c90 while provide a lot of useful gnu extension, and is supported by all modern gcc and clang.

* btrfs-progs: raid56: Introduce tables for RAID6 recoveryQu Wenruo2017-07-03
| | | | | | | | | | | | | | | | | Use kernel RAID6 galois tables for later RAID6 recovery. Galois tables file, kernel-lib/tables.c is generated by user space program, mktable. Galois field tables declaration, in kernel-lib/raid56.h, is completely copied from kernel. The mktables.c is copied from kernel with minor header/macro modification, to ensure the generated tables.c works well in btrfs-progs.

It contains 2 functions, from original btrfs-progs code: void raid6_gen_syndrome(int disks, size_t bytes, void **ptrs); int raid5_gen_result(int nr_devs, size_t stripe_len, int dest, void **data); Will be expanded later and some part of it(RAID6 recover part) may keep sync with kernel later.

* btrfs-progs: fix missing __error symbol in libbtrfs.so.0Sergei Trofimovich2017-03-31
| | | | | | | | | | | | | | | | | | | | | | | | | The easiest way to reproduce the error is to try to build btrfs-progs with $ make LDFLAGS=-Wl,--no-undefined btrfs-list.o: In function `lookup_ino_path': btrfs-list.c:(.text+0x7d2): undefined reference to `__error' Noticed by Denis Descheneaux when snapper tool stopped working after upgrade to btrfs-progs-4.10. As soname didn't change in 4.9 -> 4.10 release I assume it's just an object file omission in library depends and not the API/ABI change of the library error printing.

| | | | | | | | | | | | | The patch "btrfs-progs: Introduce kernel sizes to cleanup large intermediate number" (a2203246ae483d09) was taken from kernel but not properly ported so the build breaks because the header linux/sizes.h is not exported.

* btrfs-progs: drop feature defines from C files, in favour of CFLAGS definesDimitri John Ledkov2015-01-27
| | | | | | | | | | | | | | | | | | | | | | glibc 2.10+ (5+ years old) enables all the desired features: _XOPEN_SOURCE 700, __XOPEN2K8, POSIX_C_SOURCE, DEFAULT_SOURCE; with a single _GNU_SOURCE define in the makefile alone. For portability to other libc implementations (e.g. dietlibc) _XOPEN_SOURCE=700 is also defined. This also resolves Debian bug report filed by Michael Tautschnig - "Inconsistent use of _XOPEN_SOURCE results in conflicting declarations". Whilst I was not able to reproduce the results, the reported fact is that _XOPEN_SOURCE set to 500 in one set of files (e.g. cmds-filesystem.c) generates/defines different struct stat from other files (cmds-replace.c). This patch thus cleans up all feature defines, and sets them at a consistent level.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | format This patch adds some functions to manage the printing of the data in tabular format. The function struct string_table *table_create(int columns, int rows) creates an (empty) table. The functions char *table_printf(struct string_table *tab, int column, int row, char *fmt, ...) char *table_vprintf(struct string_table *tab, int column, int row, char *fmt, va_list ap) populate the table with text. To align the text to the left, the text shall be prefixed with '<', otherwise the text shall be prefixed by a '>'. If the first character is a '=', the the text is replace by a sequence of '=' to fill the column width. The function void table_free(struct string_table *) frees all the data associated to the table. The function void table_dump(struct string_table *tab) prints the table on stdout. Signed-off-by: Goffredo Baroncelli <kreijack@inwind.it> Signed-off-by: David Sterba <dsterba@suse.cz>

* btrfs-progs: Improve static building and installationThomas Petazzoni2014-09-02
| | | | | | | | | | | | | | | | | | | | | | | | | This commit improves the static-only building of btrfs-progs, and adds support for installing the static only tools: - It now ensures that all programs are built statically, not only a small subset of them, by defining 'progs_static' from the existing 'progs' variable. - It changes the order of libraries in the btrfs-%.static rule so that -lpthread (part of STATIC_LIBS) appears *after* the '$($(subst -,_,$(subst .static,,$@)-libs))' logic, which brings in -lcom_err. This is needed because libcom_err.a uses the semaphore functions, which are available in the pthread library. - Adds the necessary rules to generate the btrfsck.static link and btrfstune.static binary. - Adds an 'install-static' target to install the static binaries. Note that they are renamed to not carry a '.static' suffix. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: David Sterba <dsterba@suse.cz>
