2019-09-26Revert "Improve ptrace-error detection on Linux targets"Sergio Durigan Junior16-487/+31

2019-09-26Improve ptrace-error detection on Linux targetsSergio Durigan Junior16-31/+487
In Fedora GDB, we carry the following patch: https://src.fedoraproject.org/rpms/gdb/blob/8ac06474ff1e2aa4920d14e0666b083eeaca8952/f/gdb-attach-fail-reasons-5of5.patch Its purpose is to try to detect a specific scenario where SELinux's 'deny_ptrace' option is enabled, which prevents GDB from ptrace'ing in order to debug the inferior (PTRACE_ATTACH and PTRACE_TRACEME will fail with EACCES in this case). I like the idea of improving error detection and providing more information to the user (a simple "Permission denied" can be really frustrating), but I don't fully agree with the way the patch was implemented: it makes GDB link against libselinux only for the sake of consulting the 'deny_ptrace' setting, and then prints a warning if ptrace failed and this setting is on. My first thought (and attempt) was to make GDB print a generic warning when a ptrace error happened; this message would just point the user to our documentation, where she could find more information about possible causes for the error (and try to diagnose/fix the problem). This proved to be too simple, and I was convinced that it is actually a good idea to go the extra kilometre and try to pinpoint the specific problem (or problems) preventing ptrace from working, as well as provide useful suggestions on how the user can fix things. Here is the patch I came up with. It implements a new function, 'linux_ptrace_restricted_fail_reason', which does a few things to check what's wrong with ptrace: - It dlopen's "libselinux.so.1" and checks if the "deny_ptrace" option is enabled. - It reads the contents of "/proc/sys/kernel/yama/ptrace_scope" and checks if it's different than 0. For each of these checks, if it succeeds, the user will see a message informing about the restriction in place, and how it can be disabled. For example, if "deny_ptrace" is enabled, the user will see: # gdb /usr/bin/true ... Starting program: /usr/bin/true warning: Could not trace the inferior process. warning: ptrace: Permission denied The SELinux 'deny_ptrace' option is enabled and preventing GDB from using 'ptrace'. You can disable it by executing (as root): setsebool deny_ptrace off If you are debugging the inferior remotely, the ptrace restriction(s) need to be disabled in the target system (e.g., where GDBserver is running). During startup program exited with code 127. (gdb) In case "/proc/sys/kernel/yama/ptrace_scope" is > 0: # gdb /usr/bin/true ... Starting program: /usr/bin/true warning: Could not trace the inferior process. warning: ptrace: Operation not permitted The Linux kernel's Yama ptrace scope is in effect, which can prevent GDB from using 'ptrace'. You can disable it by executing (as root): echo 0 > /proc/sys/kernel/yama/ptrace_scope If you are debugging the inferior remotely, the ptrace restriction(s) need to be disabled in the target system (e.g., where GDBserver is running). During startup program exited with code 127. (gdb) If both restrictions are enabled, both messages will show up. This works for gdbserver as well, and actually fixes a latent bug I found: when ptrace is restricted, gdbserver would hang due to an unchecked ptrace call: # gdbserver :9988 /usr/bin/true gdbserver: linux_ptrace_test_ret_to_nx: Cannot PTRACE_TRACEME: Operation not permitted gdbserver: linux_ptrace_test_ret_to_nx: status 256 is not WIFSTOPPED! gdbserver: linux_ptrace_test_ret_to_nx: failed to kill child pid 2668100 No such process [ Here you would have to issue a C-c ] Now, you will see: # gdbserver :9988 /usr/bin/true gdbserver: linux_ptrace_test_ret_to_nx: Cannot PTRACE_TRACEME: Permission denied gdbserver: linux_ptrace_test_ret_to_nx: status 256 is not WIFSTOPPED! gdbserver: linux_ptrace_test_ret_to_nx: failed to kill child pid 2766868 No such process gdbserver: Could not trace the inferior process. gdbserver: ptrace: Permission denied The SELinux 'deny_ptrace' option is enabled and preventing GDB from using 'ptrace'. You can disable it by executing (as root): setsebool deny_ptrace off If you are debugging the inferior remotely, the ptrace restriction(s) need to be disabled in the target system (e.g., where GDBserver is running). # (I decided to keep all the other messages, even though I find them a bit distracting). If GDB can't determine the cause for the failure, it will still print the generic error message which tells the user to check our documentation: There might be restrictions preventing ptrace from working. Please see the appendix "Linux kernel ptrace restrictions" in the GDB documentation for more details. If you are debugging the inferior remotely, the ptrace restriction(s) need to be disabled in the target system (e.g., where GDBserver is running). This means that the patch expands our documentation and creates a new appendix section named "Linux kernel ptrace restrictions", with sub-sections for each possible restriction that might be in place. Notice how, on every message, we instruct the user to "do the right thing" if gdbserver is being used. This is because if the user started gdbserver *before* any ptrace restriction was in place, and then, for some reason, one or more restrictions get enabled, then the error message will be displayed both on gdbserver *and* on the connected GDB. Since the user will be piloting GDB, it's important to explicitly say that the ptrace restrictions are enabled in the target, where gdbserver is running. The current list of possible restrictions is: - SELinux's 'deny_ptrace' option (detected). - YAMA's /proc/sys/kernel/yama/ptrace_scope setting (detected). - seccomp on Docker containers (I couldn't find how to detect). It's important to mention that all of this is Linux-specific; as far as I know, SELinux, YAMA and seccomp are Linux-only features. I tested this patch locally, on my Fedora 30 machine (actually, a Fedora Rawhide VM), but I'm not proposing a testcase for it because of the difficulty of writing one.

2019-09-26Do not expose stub types to PythonTom Tromey7-0/+132
dwarf2read.c will create stub types for Ada "Taft Amendment" types. These stub types can currently be exposed to Python code, where they show up as TYPE_CODE_VOID types (but that, mysteriously, can sometimes be used in other ways). While it's possible to work with such types by using strip_typedefs, this seemed unpleasant to me. This patch takes another approach instead, which is to try not to expose stub types to Python users. gdb/ChangeLog 2019-09-26 Tom Tromey <tromey@adacore.com> * python/py-type.c (type_to_type_object): Call check_typedef for stub types. gdb/testsuite/ChangeLog 2019-09-26 Tom Tromey <tromey@adacore.com> * gdb.ada/py_taft.exp: New file. * gdb.ada/py_taft/main.adb: New file. * gdb.ada/py_taft/pkg.adb: New file. * gdb.ada/py_taft/pkg.ads: New file.

2019-09-24[gdb/tdep] Handle mxcsr kernel bug on Intel Skylake CPUsTom de Vries4-2/+34
On my openSUSE Leap 15.1 x86_64 Skylake system with the default (4.12) kernel, I run into: ... FAIL: gdb.base/gcore.exp: corefile restored all registers ... The problem is that there's a difference in the mxcsr register value before and after the gcore command: ... - mxcsr 0x0 [ ] + mxcsr 0x400440 [ DAZ OM ] ... This can be traced back to amd64_linux_nat_target::fetch_registers, where xstateregs is partially initialized by the ptrace call: ... char xstateregs[X86_XSTATE_MAX_SIZE]; struct iovec iov; amd64_collect_xsave (regcache, -1, xstateregs, 0); iov.iov_base = xstateregs; iov.iov_len = sizeof (xstateregs); if (ptrace (PTRACE_GETREGSET, tid, (unsigned int) NT_X86_XSTATE, (long) &iov) < 0) perror_with_name (_("Couldn't get extended state status")); amd64_supply_xsave (regcache, -1, xstateregs); ... after which amd64_supply_xsave is called. The amd64_supply_xsave call is supposed to only use initialized parts of xstateregs, but due to a kernel bug on intel skylake (fixed from 4.14 onwards by commit 0852b374173b "x86/fpu: Add FPU state copying quirk to handle XRSTOR failure on Intel Skylake CPUs") it can happen that the mxcsr part of xstateregs is not initialized, while amd64_supply_xsave expects it to be initialized, which explains the FAIL mentioned above. Fix the undetermined behaviour by initializing xstateregs before calling ptrace, which makes sure we get a 0x0 for mxcsr when this kernel bug occurs, and which also happens to fix the FAIL. Furthermore, add an xfail for this FAIL which triggers the same kernel bug: ... FAIL: gdb.arch/amd64-init-x87-values.exp: check_setting_mxcsr_before_enable: \ check new value of MXCSR is still in place ... Both FAILs pass when using a 5.3 kernel instead on the system mentioned above.

2019-09-20Change TUI window commands to be case-sensitiveTom Tromey4-95/+77
The TUI window-related commands like "focus" are case insensitive. This is not the norm in gdb, and I don't see a good reason to have it here. This patch changes the TUI to be case sensitive, like the rest of gdb. gdb/ChangeLog 2019-09-20 Tom Tromey <tom@tromey.com> * NEWS: Mention case-sensitivity of TUI commands. * tui/tui-win.c (tui_set_focus_command): Now case-sensitive.

Commit e594a5d1 ("Turn two locator functions into methods") turned set_locator_fullname into a method on tui_locator_window. I missed it at the time, but this change allows for the removal of a call to tui_locator_win_info_ptr. gdb/ChangeLog 2019-09-20 Tom Tromey <tom@tromey.com> * tui/tui-stack.c (tui_locator_window::set_locator_fullname): Don't call tui_locator_win_info_ptr.
2019-09-20Don't call refresh in tui_resize_allTom Tromey2-1/+4
There's no reason to call refresh in tui_resize_all. This call flushes the curses window contents to the terminal -- but, because we're about the resize all the windows, we're going to be sending more data to the terminal momentarily. This patch removes the call. gdb/ChangeLog 2019-09-20 Tom Tromey <tom@tromey.com> * tui/tui-win.c (tui_resize_all): Don't call refresh.
2019-09-20Set TUI locator height to 1Tom Tromey4-17/+19
The TUI has long had code to resize the locator, using 2 as the height. However the code has "1" in a comment, like: locator->resize (2 /* 1 */ , This patch fixes the resizing code to set the height to 1. Doing this revealed what was probably the reason for setting the height to 2 in the first place: this caused the locator window to scroll. However, this is easily handled by calling scrollok on the locator window. gdb/ChangeLog 2019-09-20 Tom Tromey <tom@tromey.com> * tui/tui-win.c (tui_resize_all, tui_adjust_win_heights): Use 1 as height for locator. * tui/tui-stack.c (tui_locator_window::rerender): Call scrollok. * tui/tui-layout.c (show_source_disasm_command, show_data) (show_source_or_disasm_and_command): Use 1 as height for locator.

tui_source_window_base::show_source_content is not used outside the class any more, so this makes it private. Examining the callers shows that it can't be called without source contents, so it can be simplified as well. gdb/ChangeLog 2019-09-20 Tom Tromey <tom@tromey.com> * tui/tui-winsource.h (struct tui_source_window_base) <show_source_content>: Now private. * tui/tui-winsource.c (tui_source_window_base::show_source_content): Don't handle empty content case.

A couple of spots in tui-layout.c still call the show_source_content method.

2019-09-20Change tui_make_status_line to be a methodTom Tromey3-18/+28
This changes tui_make_status_line to be a method on tui_locator_window. This is a minor cleanup. This also changes the new method to use the locator's width, rather than the terminal width. This is important if we ever want to allow windows to be made more narrow. gdb/ChangeLog 2019-09-20 Tom Tromey <tom@tromey.com> * tui/tui-stack.h (struct tui_locator_window) <make_status_line>: Declare. * tui/tui-stack.c (tui_locator_window::make_status_line): Rename from tui_make_status_line.

This can however match "FOOBAR", so perhaps "\$FOOBAR^" would have been a better choice.

2019-09-19[gdb] Catch exception when constructing the highlighterTom de Vries2-6/+12
Currently in source_cache::ensure we catch the exception that triggers when highlighter->highlight is called: ... try { std::istringstream input (contents); std::ostringstream output; highlighter->highlight (input, output, lang_name, fullname); ... and the file used earlier in the construction of the highlighter: ... highlighter = new srchilite::SourceHighlight ("esc.outlang"); ... is missing. The fact that this exception triggers when highlighter->highlight is called is an implementation artefact of libsource-highlight.so though, and this could be different for older or newer versions. Make things more robust by also catching exceptions thrown during construction of the highlighter. This makes the handling on master equivalent with what has been committed for 8.3.1.

2019-09-19bfd_section_* macrosAlan Modra62-460/+429
This large patch removes the unnecessary bfd parameter from various bfd section macros and functions. The bfd is hardly ever used and if needed for the bfd_set_section_* or bfd_rename_section functions can be found via section->owner except for the com, und, abs, and ind std_section special sections. Those sections shouldn't be modified anyway. The patch also removes various bfd_get_section_<field> macros, replacing their use with bfd_section_<field>, and adds bfd_set_section_lma. I've also fixed a minor bug in gas where compressed section renaming was done directly rather than calling bfd_rename_section. This would have broken bfd_get_section_by_name and similar functions, but that hardly mattered at such a late stage in gas processing. bfd/ * bfd-in.h (bfd_get_section_name, bfd_get_section_vma), (bfd_get_section_lma, bfd_get_section_alignment), (bfd_get_section_size, bfd_get_section_flags), (bfd_get_section_userdata): Delete.

2019-09-19[gdb/testsuite] Fix gdb_target_cmdTom de Vries2-2/+6
In commit 81dc3ab594 "[gdb/testsuite] Handle unreachable network in server-connect.exp" a regression was introduced in gdb_target_cmd, causing ERRORs like this: ... ERROR: tcl error sourcing src/gdb/testsuite/gdb.server/abspath.exp. ERROR: wrong # args: should be "gdb_target_cmd {$args}" while executing "gdb_target_cmd $gdbserver_protocol $gdbserver_gdbport" ... Fix the argument passing in gdb_target_cmd. Tested on x86_64-linux. gdb/testsuite/ChangeLog: 2019-09-19 Tom de Vries <tdevries@suse.de> * lib/gdbserver-support.exp (gdb_target_cmd): Fix argument passing.
