* Use system-level values for Windows virtual memory (#2077)Daniel Widdis2022-10-211-0/+4
| | | | | | | | | | | | | | | | | * Use system-level values for Windows virtual memory Submitting this as a draft PR as I believe it will address #2074. I do not have either a C or Python development environment to test these changes, so they are provided in the hopes someone else can test and confirm they fix the issue. There's probably some room to simplify the code with temporary variables to reduce redundancy. For background, I have implemented precisely this logic in my own (Java-based) project [here](https://github.com/oshi/oshi/blob/3bb9eafbe2062edad4108b7b12501b1f9be27361/oshi-core/src/main/java/oshi/hardware/platform/windows/WindowsVirtualMemory.java#L110-L118) and [here](https://github.com/oshi/oshi/blob/3bb9eafbe2062edad4108b7b12501b1f9be27361/oshi-core/src/main/java/oshi/hardware/platform/windows/WindowsGlobalMemory.java#L253-L263) following a detailed investigation in https://github.com/oshi/oshi/issues/1182 Signed-off-by: Daniel Widdis <widdis@gmail.com> * Formatting, credits, change log Signed-off-by: Daniel Widdis <widdis@gmail.com> Signed-off-by: Daniel Widdis <widdis@gmail.com>

* Resolve race condition in Process.threads() (#2151)Daniel Li2022-09-291-0/+3
| | | | | | | | | | | | | | | | | * Resolve race condition in Process.threads() Process.threads() has a race condition triggered when a thread exits after the open_binary() call and before the read() call. When this happens, the read() call raises ProcessLookupError. Handle the race condition by catching ProcessLookupError from read() and treating the same as a FileNotFoundError from open_binary(). This is the same approach used in ppid_map(). Signed-off-by: Daniel Li <daniel.li@deshaw.com> * Also catch ProcessLookupError in open_files() Signed-off-by: Daniel Li <daniel.li@deshaw.com>
* [macOS] Fix out-of-bounds read around sysctl_procargs (#2135)Bernhard Urban-Forster2022-09-191-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The buffer size is initially determined by querying `argmax`: https://github.com/giampaolo/psutil/blob/9f9a82d02c901f62512236b44edb050f84cbe5b6/psutil/arch/osx/process_info.c#L260-L265 This length is passed to the `sysctl()` call for querying the procargs. `sysctl()` is allowed to set it to a smaller value, to indicate the buffer wasn't fully used. However this is not passed back to the caller "owning" that memory, and also parsing the result. Depending on the allocator, it's possible that we can observe "garbage" values, consider this example: ```python import psutil import subprocess import os import sys environment_cookie = "__MAGIC_ENV_COOKIE__" for i in range(0,200): os.environ["PATH"] = os.environ.get("PATH", "") + os.pathsep + environment_cookie + str(i) print("sys.executable: " + str(sys.executable)) exe = os.path.split(sys.executable)[1] exe = exe.split(".")[0] print("exe: " + str(exe)) polluted_process = subprocess.Popen([exe, "-c", "import time; time.sleep(3)"], env=os.environ.copy()) clean_process = subprocess.Popen([exe, "-c", "import time; time.sleep(3)"], env={}) print("polluted pid=" + str(polluted_process.pid)) print("clean pid=" + str(clean_process.pid)) pp = psutil.Process(polluted_process.pid) pc = psutil.Process(clean_process.pid) for i in range(0,8): pp.environ() for i in range(0,8): e = pc.environ() if len(e) > 0: print("clean subprocess (should be empty) env=" + str(e)) exit(2) print("no repro, try again :-/") ``` In order to better illustrate the problem, I added this debug output to `psutils`: ```diff +++ psutil/arch/osx/process_info.c @@ -263,6 +263,7 @@ psutil_get_environ(pid_t pid) { goto error; procargs = (char *)malloc(argmax); + printf("[psutil_get_environ] pid=%d, procargs=%p\n", pid, procargs); if (NULL == procargs) { PyErr_NoMemory(); goto error; ``` Example output: ``` $ python3 .py sys.executable: /opt/homebrew/opt/python@3.10/bin/python3.10 exe: python3 polluted pid=63479 clean pid=63480 [psutil_get_environ]

* Handle ENAMETOOLONG on Linux (#1940) (#1955)Nikita Radchenko2021-10-051-1/+5
| | | | | | | | | | | | | | | When resolving process file descriptors symlinks in procfs (/proc/PID/fd/FD), the kernel can only deal with file paths no longer than PAGE_SIZE (which usually equals to PATH_MAX). https://elixir.bootlin.com/linux/v5.12/source/fs/proc/base.c#L1759 Resolving fd symlink that corresponds to a file with a path longer than PATH_MAX with readlink(2) would result in ENAMETOOLONG error (see details in #1940). We can do nothing to fix this in userspace; therefore these errors should be ignored.
