3 * Bug fixes, Linux ioctl updates.
4 * David Miller contributed support for Linux/SPARC64.
12 * Update Linux ioctl lists.
13 * Update PF_* and AF_* value lists.
14 * The 4.5.3 -p behavior for NPTL threads applies only under -f, and got fixed.
19 * On Linux using NPTL threads, -p will now attach to all threads in a process.
20 * Handle new mq_* system calls in Linux 2.6.6 and later.
25 * Report some new VM_* bit values on Linux.
26 * Better output for Linux sched_* system calls.
31 * Display multiple ioctl name matches on Linux.
35 * New port to AMD's x86-64 architecture. One strace binary can
36 handle both new x86-64 and old i386 processes.
37 * Fixed support for LFS64 calls.
38 * New switch -E to add/remove environment variables for the command.
39 * Merged s390/s390x port.
40 * Trace an unbounded number of processes.
41 * Handle numerous new system calls in Linux 2.5, and new threads semantics.
42 * Fixed bugs with attach/detach leaving things stopped.
43 * Fixed traced process seeing ECHILD despite live, traced children
44 in waitpid calls with WNOHANG.
45 * Stuart Menefy contributed a port to Linux/SH.
46 * Stephen Thomas contributed a port to Linux/SH64.
47 * Many other bug fixes.
51 * Fix Linux/ia64 support, looks like someone renamed a few things on us
52 * Fix the ioctl setup for Linux, turned out it did not really work.
53 Improve the ioctl extracter as well so we decode some more ones.
57 * compile fixes for Linux/mips
61 * Linux ia64 and hppa ports added
62 * The usual Linux syscall updates (includes 32bit uid/gid support),
63 * Linux ioctl list updated
64 * Support IPv6 scope ids
65 * FreeBSD/i386 port added
66 * UnixWare and Solaris updates
67 * Better support for tracing multithreaded processes in Linux
71 * Compiles on glibc2.0 systems again
72 * Linux/S390 port added
73 * The usual Linux syscall updates
74 * we can follow fork on arm now
78 * Linux/MIPS port added
79 * Lots of Linux updates again
80 * Improved IPv6 support
86 * Compiles on glibc2.0 systems again
90 * Get stat structure properly on Linux 64bit archs
91 * Personalities work again
92 * Compile correctly on SunOS again
98 * Linux (ultra)sparc fixes
105 * add support for more Linux architectures (powerpc, sparc, arm)
106 * support lots more Linux syscalls
107 * fix signal handling
108 * add IPX and IPIP support
109 * check stray syscall after execv
110 * fix hanging children
112 Changes in version 3.1
113 ======================
116 * Linux 68k is supported
117 * Linux alpha is supported
118 * configure is upgraded to autoconf 2.x
119 * using -f in combination with -e now works correctly
120 * output can be piped to a program
121 * tracing setuid programs works better
122 * it is now reasonable to install strace setuid to root in some circumstances
123 * new useful tracing names like file and process to trace whole
124 classes of system calls, e.g. -efile traces all system calls that
125 take a file name as an argument
126 * IPC calls on SunOS 4.1.x are decoded
127 * Linux program memory is reliably dereferenced
128 * Linux decodes at least the name of all syscalls as of pre2.0.4
129 * various cosmetic changes and bug fixes
131 Changes from versions 2.x to version 3.0
132 ========================================
134 * filename arguments are neither abbreviated nor stringified
135 * string arguments are now true C strings using octal instead of hex by default
136 * preprocessor constants are never shortened (e.g. was RDONLY => now O_RDONLY)
137 * by default the output for multiple processes now goes into one file
138 * all structures, vectors, bitsets, etc. use consistent output formats
139 * the -c option now means count calls, -i does what the old -c used to do
141 New Features in version 3.0
142 ===========================
144 * non-ascii strings can be optionally printed entirely in hex
145 * the output format is readable when mutiple processes are generating output
146 * exit values are printed in an alignment column
147 * is is possible to suppress messages about attaching and detaching
148 * various tracing features can be enabled on a per syscall/signal/desc basis
149 * selective tracing of syscalls
150 * selective printing of syscall structures
151 * selective abbreviation of long structures on a per syscall basis
152 * selective printing of raw syscall arguments and results
153 * selective tracing of signals
154 * selective dumping of all I/O read from file descriptors
155 * selective dumping of all I/O written to file descriptors
156 * optional counting of time, calls, and errors for each syscall
