Author: jkoshy
Date: 2008-04-07 05:24:33 -0700 (Mon, 07 Apr 2008)
Log Message:
-----------
- Correctly handle sections of type SHT_NOBITS. For these sections:
- elf_getdata() and elf_rawdata() should return an "Elf_Data" structure
that has its "d_buf" member set to NULL and "d_size" member set to
the nominal 'size' of the section. [1]
- Update the manual page for these functions.
Submitted by: kaiwang27 [1]
- Fix a memory leak in an error handling path inside elf_getdata().
- Use _libelf_allocate_data() in elf_newdata() for consistency.
Modified Paths:
--------------
projects/libelf/trunk/elf_data.c

+.Os
+.Sh NAME
+.Nm size
+.Nd "display section sizes and total size in"
+.Tn ELF
+files.
+.Sh SYNOPSIS
+.Nm
+.Op Fl Adhotx
+.Op Ar
+.Sh DESCRIPTION
+The
+.Nm
+utility
+lists the size of various sections and total size (if choosen) for each input
+.Ar file.
+The
+.Nm
+utility can operate on ELF object,
+.Xr ar 1
+archives, and core dumps.
+.Pp
+If no file name is specified in the input, "a.out" is assumed.
+.Pp
+The following options are available:
+.Bl -tag -width indent
+.It Fl A
+The output of
+.Nm
+will resemble output from System V
+.Nm .
+By default, one line of output is generated for each ELF object or each module
+in an archive, if this option is not choosen.
+.It Fl t
+Shows cumulative totals of section sizes from all objects. Not available when
+System V output format
+.Fl A
+is choosen.
+.It Fl d | Fl o | Fl x
+The section sizes can be displayed either in decimal, octal or hexadecimal by
+choosing one of these options. Totals
+.Fl t
+are always displayed in two radixes; decimal and hexadecimal for
+.Fl d
+or
+.Fl x
+output, or octal and hexadecimal if
+.Fl o
+is choosen.
+.It Fl h
+This prints a usage summary and exits.
+.El
+.Sh EXIT STATUS
+.Ex -std
+.Sh EXAMPLES
+The following are examples of typical usage
+of the
+.Nm
+command:
+.Pp
+.Dl "$ size /bin/ls"
+.Dl "text data bss dec hex filename"
+.Dl "20975 540 392 21907 5593 /bin/ls"
+.Pp
+.Dl "$ size -tx /bin/ls /bin/dd"
+.Dl "text data bss dec hex filename"
+.Dl "0x51ef 0x21c 0x188 21907 5593 /bin/ls"
+.Dl "0x3df5 0x170 0x200 16741 4165 /bin/dd"
+.Dl "0x8fe4 0x38c 0x388 38648 96f8 (TOTALS)"
+.Sh SEE ALSO
+.Xr ar 1 ,
+.Xr objdump 1 ,
+.Xr readelf 1
+.Rs
+.%A "AT&T Unix Systems Labs"
+.%T "System V Application Binary Interface"
+.%O http://www.sco.com/developers/gabi/
+.Re
+.Sh HISTORY
+The
+.Nm
+utility first appeared in
+.At v6.
+The last FreeBSD
+.Nm
+was discontinued in
+.Fx v5 ,
+when i386-only a.out format was dropped in favor of ELF.
+.Sh AUTHORS
+.An -nosplit
+The
+.Nm
+utility was re-written by
+.An S.Sam Arun Raj Aq sam...@gm...
+This manual page was written by
+.An S.Sam Arun Raj Aq sam...@gm...
+.Sh LIMITATIONS
+Unlike the GNU
+.Nm
+this doesn't support multiple object file formats, only ELF using the
+.Xr elf 3
+and
+.Xr gelf 3
+API's.

+.Sh NAME
+.Nm strings
+.Nd "print the strings of printable characters in files"
+.Sh SYNOPSIS
+.Nm
+.Op Fl afho
+.Op Fl e Ar encoding
+.Op Fl n Ar number
+.Op Fl t Ar radix
+.Op Ar
+.Sh DESCRIPTION
+Fo each
+.Ar file
+given, the
+.Nm
+utility prints any contiguous seqeunce of printable
+characters of atleast 'n' characters long (the default is 4 characters)
+followed by an unprintable character.
+.Nm
+only scans the initialized and loaded sections of ELF objects; for other
+file types, the entire file is scanned.
+The
+.Nm
+utility is mainly useful for determining the contents of non-text files.
+.Pp
+If no file name is specified in the input, standard input is read from.
+.Pp
+The following options are available:
+.Bl -tag -width indent
+.It Fl a
+This option instructs
+.Nm
+to scan the entire file. This is useful to override the default behaviour of
+scanning only initialized and loaded section of ELF objects.
+.It Fl e Ar encoding
+Select the character encoding to be used while searching for strings.
+The encoding depends on the single character argument which speicifes
+the encoding;
+.Ar s
+for single 7-bit-byte characters (ASCII, ISO 8859, etc., default).
+.Ar S
+for single 8-bit-byte characters.
+.Ar l
+for 16-bit littleendian.
+.Ar b
+for 16-bit bigendian.
+.Ar L
+for 32-bit littleendian.
+.Ar B
+for 32-bit bigendian.
+.It Fl f
+Print the name of the file before each string.
+.It Fl t Ar radix
+Print the offset from the start of the file before each string. The
+format depends on the single character argument which specifies the
+radix of the offset;
+.Ar d
+for decimal,
+.Ar o
+for octal,
+.Ar x
+for hexadecimal.
+.It Fl n Ar number
+Print the contiguous character sequence of alteast
+.Ar number
+characters long, instead of default 4 characters.
+.It Fl o
+This is same as -t o.
+.It Fl h
+This prints a usage summary and exits.
+.El
+.Sh EXIT STATUS
+.Ex -std
+.Sh EXAMPLES
+The following are examples of typical usage
+of the
+.Nm
+command:
+.Dl ""
+.Dl "$ strings /bin/ls"
+.Dl "$ strings -a /bin/ln"
+.Dl "$ strings -a -f -t x /bin/cat"
+.Sh SEE ALSO
+.Xr ar 1 ,
+.Xr nm 1 ,
+.Xr objdump 1 ,
+.Xr ranlib ,
+.Xr readelf 1
+.Sh HISTORY
+The first FreeBSD
+.Nm
+utility appeared in
+.Fx v3.
+It was later discontinued in
+.Fx v5 ,
+when i386-only a.out format was dropped in favor of ELF.
+.Sh AUTHORS
+.An -nosplit
+The
+.Nm
+utility was re-written by
+.An S.Sam Arun Raj Aq sam...@gm...
+This manual page was written by
+.An S.Sam Arun Raj Aq sam...@gm...
+.Sh LIMITATIONS
+Unlike the GNU
+.Nm
+this doesn't support multiple object file formats, only ELF using the
+.Xr elf 3
+and
+.Xr gelf 3
+API's.

+: README
+
+This directory contains a test suite for libelf.
+
+: Pre-requisites
+
+1) TET (Test Execution Toolkit) from The Open Group.
+ http://tetworks.opengroup.org/tet/
+
+2) YAML tools for Python.
+ http://pyyaml.org
+
+On FreeBSD, you may install the following ports:
+ - misc/tet, version 3.7 or later
+ - devel/py-yaml, version 3.04 or later
+
+
+: Notes on TET Configuration
+
+Debugging TET executables is much easier if you've built
+the 'lite' version of TET. The LibElf test suite does not
+use TET's distributed testing features, so the 'lite' version
+of TET is sufficient.
+
+The 'lite' version of TET does not need further configuration.
+
+If you chosen to install the 'inet' (distributed) version of TET,
+you'll need a minimal ${TET_ROOT}/systems file. The following
+content in the file is enough for this test suite.
+
+ 000 localhost
+
+For the 'inet' version of TET, you'll need `tccd` running, and a
+`systems.equiv` file in the directory of the user running `tccd`.
+The following contents will do for this file:
+
+ localhost
+
+We use regular 'make' as our build tool. Since make doesn't use
+the TETware API when printing messages we must tell tcc to execute
+make with output capture mode enabled.
+
+TET_BUILD_TOOL=make
+TET_OUTPUT_CAPTURE=True
+
+We'll assume that each test case is in a directory of its
+own and the Makefile in that directory builds that executable
+We don't need the name of the test case to be passed in to 'make'
+
+TET_PASS_TC_NAME=False
+
+Similarly, for cleaning the test suite, we use 'make'.
+
+TET_CLEAN_TOOL=make
+TET_CLEAN_FILE=clean
+
+Since the test cases themselves are API compliant, we'll
+set TET_OUTPUT_CAPTIRE=False for test case execution.
+
+: Notes on TET execution
+
+Edit the top-level 'Makefile' and set the TET_ROOT variable to
+the path where the TET test suite is installed. Once this is
+done:
+
+ * A `make all` at the top level will build the test suite.
+ * A `make execute` will run `tcc`, leaving a log in a `results/`
+ directory.
+
+Here is how to run `tcc` by hand:
+
+ % TET_ROOT=/where/ever TET_EXECUTE=/usr/obj/`pwd` TET_SUITE_ROOT=`pwd` \
+ $TET_ROOT/bin/tcc [-e | -b | -c] .
+
+The TET_ROOT setting points points `tcc` to its configuration files.
+
+TET_EXECUTE points `tcc` to the location of the binaries created by the
+'build' phase. Since we are using FreeBSD `make`, this path would be
+under ${MAKEOBJDIRPREFIX}.
+
+TET_SUITE_ROOT informs `tcc` that the test suite is NOT located under
+${TET_ROOT}.
+
+If all goes well, `tcc` will create a journal file in the
+'results/NNNN[bec]/' directory under ${PWD}.

+# This script converts a textual (YAML) description of an ELF file to
+# an equivalent 'binary' file.
+#
+# The YAML description may have the following top-level keys:
+#
+# 'elf_fillchar': char
+# Sets the fill character to 'char'.
+# 'ehdr': EHDR-DESCRIPTOR
+# Defines an ELF Ehdr structure.
+# 'phdrtab': list-of(PHDR-DESCRIPTOR)
+# Defines the contents of the ELF Program Header table.
+# Each `Phdr' descriptor represents one ELF Phdr entry.
+# 'sections': list-of(SECTION-DESCRIPTOR)
+# Defines the content of each section in the file. Each
+# `SECTION-DESCRIPTOR' contains information for the
+# section `header' and the actual data for the section.
+#
+# The script will compute reasonable defaults for any fields
+# left unspecified in the YAML description.
+#
+# Descriptors EHDR-DESCRIPTOR and PHDR-DESCRIPTOR may be specified
+# as a YAML key-value set. The key names correspond to the
+# field names of the corresponding ELF structures, e.g., 'e_machine'
+# and 'e_ident' for the Ehdr and 'p_type' and 'p_paddr' for
+# a Phdr entry.
+#
+# Descriptor SECTION-DESCRIPTOR contains the fields in an ELF
+# Shdr structure and an additional member 'sh_data', whose
+# value is the data for the section.
+#
+# Example:
+#
+# <snip>
+# ehdr: !Ehdr
+# e_ident: !Ident
+# ei_class: ELFCLASS32
+# ei_data: ELFDATA2MSB
+# e_machine: EM_PPC
+# phdrtab:
+# - !Phdr
+# ph_type: PHT_NULL
+# ... other program header fields ...
+# - !Phdr
+# ... etc. ...
+# sections:
+# - !Section
+# sh_name: .dynsym
+# ... other section header fields ...
+# sh_data: # ... list of data ...
+# - !Dyn
+# d_tag: 0xdeadcode
+# - !Dyn
+# d_tag: 0xcafebabe
+# - !Section
+# sh_name: .shstrtab
+# sh_type: SHT_STRTAB
+# sh_data:
+# - string1
+# - string2
+# </snip>
+#
+# :: Handling of strings ::
+#
+# Fields like 'sh_name' (in a section header) are defined to contain
+# an integer index into a specified string table (in this case a
+# section with name '.shstrtab'). Other ELF data structures use a
+# similar convention; names in a '.dynamic' section as stored as
+# indices into a '.dynstr' section. In the YAML descriptor, such
+# fields may be specified as indices, which are used as-is, or as text
+# strings which are converted to the appropriate string index.
+# For convenience in creating ELF objects with a large number of
+# sections, a section index may be manually specified using a
+# 'sh_index' pseudo field.
