2017-04-04Support ELF SHF_GNU_MBIND and PT_GNU_MBIND_XXXH.J. Lu5-3/+61
Mark an ALLOC section, which should be placed in special memory area, with SHF_GNU_MBIND. Its sh_info field indicates the special memory type. GNU_MBIND section names start with ".mbind" so that they are placed as orphan sections by linker. All input GNU_MBIND sections with the same sh_type, sh_flags and sh_info are placed in one output GNU_MBIND section. In executable and shared object, create a GNU_MBIND segment for each GNU_MBIND section and its segment type is PT_GNU_MBIND_LO plus the sh_info value. Each GNU_MBIND segment is aligned at page boundary. The assembler syntax: .section .mbind.foo,"adx",%progbits ^ 0: Special memory type. | 'd' for SHF_GNU_MBIND. .section .mbind.foo,"adx",%progbits,0x1 ^ 1: Special memory type. | 'd' for SHF_GNU_MBIND. .section .mbind.bar,"adG",%progbits,.foo_group,comdat,0x2 ^ 2: Special memory type. | 'd' for SHF_GNU_MBIND. bfd/ * elf.c (get_program_header_size): Add a GNU_MBIND segment for each GNU_MBIND section and align GNU_MBIND section to page size.

2017-03-20readelf: Don't error on .debug files with NOBITS .dynamic section.Mark Wielaard2-6/+15
The fix for PR binutils/17512 added a check for the dynamic segment being inside the actual ELF file. If not an error message would be produced: readelf: Error: the dynamic segment offset + size exceeds the size of the file Unfortunately for separate debuginfo files it is common for the dynamic segment not being inside the file because the .dynamic section is NOBITS. Since the check is done unconditionally in process_program_headers and process_program_headers is always called (to setup dynamic_addr in case it is needed). The error is produced on any operations done on any .debug file (even if no program headers or the dynamic segment is used). If there are section headers then a cross check is done to see if the .dynamic section is NOBITS in which case dynamic_addr is set to zero without a warning or error (which is then checked first before any operation on the dynamic segement is done). Move the check for the dynamic segment being inside the actual ELF file after the cross check with the section headers to suppress the error for .debug files. binutils/ChangeLog: * readelf.c (process_program_headers): Move dynamic_addr check after .dynamic section cross check.

2017-02-24readelf: Correct version flag formattingMaciej W. Rozycki2-6/+16
Remove a trailing space or a leading pipe character from version flags printed with `readelf --version-info'. For example with the `mips-linux' target we get: $ cat ver_def.s .data .globl new_foo .type new_foo, %object new_foo: .symver new_foo, foo@@ver_foo $ cat ver_def.ver { global: *foo*; local: *; }; $ as -o ver_def.o ver_def.s $ ld -e 0 --export-dynamic --version-script=ver_def.ver -o ver_def ver_def.o $ readelf -V ver_def Version symbols section '.gnu.version' contains 4 entries: Addr: 000000000000007e Offset: 0x01007e Link: 2 (.dynsym) 000: 0 (*local*) 2 (ver_foo) 1 (*global*) 2 (ver_foo) Version definition section '.gnu.version_d' contains 2 entries: Addr: 0x0000000000000088 Offset: 0x010088 Link: 3 (.dynstr) 000000: Rev: 1 Flags: BASE Index: 1 Cnt: 1 Name: ver_def 0x001c: Rev: 1 Flags: none Index: 2 Cnt: 1 Name: ver_foo $ which includes an unnecessary space after `BASE'; both call sites already provide suitable separation from output that follows.

2017-02-24readelf: Fix incorrect "Version definition past end of section" messageMaciej W. Rozycki2-3/+14
Fix a commit 74e1a04b9787 ("More fixes for reading corrupt ELF files.") `readelf --version-info' regression that caused "Version definition past end of section" to be always printed at the end, even with good section data. For example with the `mips-linux' target we get: $ cat ver_def.s .data .globl new_foo .type new_foo, %object new_foo: .symver new_foo, foo@@ver_foo $ cat ver_def.ver { global: *foo*; local: *; }; $ as -o ver_def.o ver_def.s $ ld -e 0 --export-dynamic --version-script=ver_def.ver -o ver_def ver_def.o $ readelf -V ver_def Version symbols section '.gnu.version' contains 4 entries: Addr: 000000000000007e Offset: 0x01007e Link: 2 (.dynsym) 000: 0 (*local*) 2 (ver_foo) 1 (*global*) 2 (ver_foo) Version definition section '.gnu.version_d' contains 2 entries: Addr: 0x0000000000000088 Offset: 0x010088 Link: 3 (.dynstr) 000000: Rev: 1 Flags: BASE Index: 1 Cnt: 1 Name: ver_def 0x001c: Rev: 1 Flags: none Index: 2 Cnt: 1 Name: ver_foo Version definition past end of section $ The cause is the `if (idx + ent.vd_next <= idx)' condition introduced to ensure forward progress, which however always triggers for good version definition section data as the last entry will have its `vd_next' value set to 0. Adjust the condition then, to say `if (idx + ent.vd_next < idx)' instead and to ensure forward progress limit the number of entries processed to the size of the version definition section, removing the problematic message from output quoted above, while ensuring the original PR 17531 test case is still handled gracefully. Add a suitable test case so that we have `readelf --version-info' coverage; due to the lack of infrastructure needed to run the linker in the `binutils' test suite and limited justification to implement it add a new `readelf.exp' script to the `ld' test suite instead, intended to gather any `readelf' test cases that require the linker to be run. If ever we decide to have linker infrastructure added to the `binutils' test suite, then the script can be moved between the test suites. binutils/ * readelf.c (process_version_sections) <SHT_GNU_verdef>: Limit the number of entries processed by the section size.

So ... give these bfd-internal symbols with external linkage a _bfd_ prefix to avoid collisions in the global symbol namespace. While at it, give them names that more closely match the corresponding option name that toggles them.
