(#1070) This file was derived from FreeBSD usr.bin/sockstat/sockstat.c. The logic of socket to PID translation was copied incorrectly. The hash, that sockstat(1) utility has, is completely internal feature, it isn't part of FreeBSD API, it is just to speed things up. So, to use this hash one actually needs to create it: declare array of buckets, populate it with sockets. In the freebsd_socks.c this wasn't done. This fix doesn't create the hash, instead it removes remnants of hashing that was there in sockstat.c. It makes code more simple, but of course slower than original sockstat(1) in case if machine is running zillions of sockets. I decided to go this way simply because I am low on time to invest into psutil, and also because better first provide correct and simple implementation and then improve it, rather than jump for complexity. --- psutil/arch/bsd/freebsd_socks.c | 19 ++++++------------- 1 file changed, 6 insertions(+), 13 deletions(-) diff --git a/psutil/arch/bsd/freebsd_socks.c b/psutil/arch/bsd/freebsd_socks.c index 5c4a47df8..d60dc898f 100644 --- a/psutil/arch/bsd/freebsd_socks.c +++ b/psutil/arch/bsd/freebsd_socks.c @@ -28,7 +28,6 @@ #include "../../_psutil_common.h" #include "../../_psutil_posix.h" -#define HASHSIZE 1009 // a signaler for connections without an actual status static int PSUTIL_CONN_NONE = 128; static struct xfile *psutil_xfiles; @@ -201,14 +200,12 @@ psutil_populate_xfiles() { int -psutil_get_pid_from_sock(int sock_hash) { +psutil_get_pid_from_sock(void *sock) { struct xfile *xf; - int hash, n; + int n; + for (xf = psutil_xfiles, n = 0; n < psutil_nxfiles; ++n, ++xf) { - if (xf->xf_data == NULL) - continue; - hash = (int)((uintptr_t)xf->xf_data % HASHSIZE); - if (sock_hash == hash) + if (xf->xf_data == sock) return xf->xf_pid; } return -1; @@ -230,7 +227,6 @@ int psutil_gather_inet(int proto, PyObject *py_retlist) { const char *varname = NULL; size_t len, bufsize; void *buf; - int hash; int retry; int type; @@ -320,8 +316,7 @@ int psutil_gather_inet(int proto, PyObject *py_retlist) { char lip[200], rip[200]; - hash = (int)((uintptr_t)so->xso_so % HASHSIZE); - pid = psutil_get_pid_from_sock(hash); + pid = psutil_get_pid_from_sock(so->xso_so); if (pid < 0) continue; lport = ntohs(inp->inp_lport); @@ -377,7 +372,6 @@ int psutil_gather_unix(int proto, PyObject *py_retlist) { size_t len; size_t bufsize; void *buf; - int hash; int retry; int pid; struct sockaddr_un *sun; @@ -434,8 +428,7 @@ int psutil_gather_unix(int proto, PyObject *py_retlist) { if (xup->xu_len != sizeof *xup) goto error; - hash = (int)((uintptr_t) xup->xu_socket.xso_so % HASHSIZE); - pid = psutil_get_pid_from_sock(hash); + pid = psutil_get_pid_from_sock(xup->xu_socket.xso_so); if (pid < 0) continue; From 0bcd10144db472682b2bb0c0b3cba3e193094a0b Mon Sep 17 00:00:00 2001 From: Giampaolo Rodola Date: Tue, 16 May 2017 13:53:03 +0200 Subject: [PATCH 1051/1297] give CREDITS to @glebius --- CREDITS | 2 ++ HISTORY.rst | 2 ++ 2 files changed, 4 insertions(+) diff --git a/CREDITS b/CREDITS index a514d7ee1..515ba38d9 100644 --- a/CREDITS +++ b/CREDITS @@ -30,6 +30,8 @@ Github usernames of people to CC on github when in need of help. - ryoqun, Ryo Onodera - OpenBSD: - landryb, Landry Breuil +- FreeNBSD: + - glebius, Gleb Smirnoff (#1013) - OSX: - whitlockjc, Jeremy Whitlock - Windows: diff --git a/HISTORY.rst b/HISTORY.rst index eeb38bec7..33f8db8ec 100644 --- a/HISTORY.rst +++ b/HISTORY.rst @@ -28,6 +28,8 @@ - 1007_: [Windows] boot_time() can have a 1 sec fluctuation between calls; the value of the first call is now cached so that boot_time() always returns the same value if fluctuation is <= 1 second. +- 1013_: [FreeBSD] psutil.net_connections() may return incorrect PID.

This not only removes ugly workaround from test_connections.py, but also fixes several failures in this test. Without file descriptor value, two local sockets connected to each other, would be equal objects. Since in the _psbsd.py:net_connections(), the returned value is a Python set, it will exclude any duplicates, resulting in shrinked list of sockets. --- psutil/arch/freebsd/sys_socks.c | 30 ++++++++++++++++-------------- psutil/tests/__init__.py | 2 +- psutil/tests/test_connections.py | 4 ---- 3 files changed, 17 insertions(+), 19 deletions(-) diff --git a/psutil/arch/freebsd/sys_socks.c b/psutil/arch/freebsd/sys_socks.c index 3387838e9..e0e2046be 100644 --- a/psutil/arch/freebsd/sys_socks.c +++ b/psutil/arch/freebsd/sys_socks.c @@ -57,16 +57,16 @@ psutil_populate_xfiles() { } -int -psutil_get_pid_from_sock(void *sock) { +struct xfile * +psutil_get_file_from_sock(void *sock) { struct xfile *xf; int n; for (xf = psutil_xfiles, n = 0; n < psutil_nxfiles; ++n, ++xf) { if (xf->xf_data == sock) - return xf->xf_pid; + return xf; } - return -1; + return NULL; } @@ -129,7 +129,8 @@ int psutil_gather_inet(int proto, PyObject *py_retlist) { } while (xig->xig_gen != exig->xig_gen && retry--); for (;;) { - int lport, rport, pid, status, family; + struct xfile *xf; + int lport, rport, status, family; xig = (struct xinpgen *)(void *)((char *)xig + xig->xig_len); if (xig >= exig) @@ -174,8 +175,8 @@ int psutil_gather_inet(int proto, PyObject *py_retlist) { char lip[200], rip[200]; - pid = psutil_get_pid_from_sock(so->xso_so); - if (pid < 0) + xf = psutil_get_file_from_sock(so->xso_so); + if (xf == NULL) continue; lport = ntohs(inp->inp_lport); rport = ntohs(inp->inp_fport); @@ -203,13 +204,13 @@ int psutil_gather_inet(int proto, PyObject *py_retlist) { goto error; py_tuple = Py_BuildValue( "(iiiNNii)", - -1, // fd + xf->xf_fd, // fd family, // family type, // type py_laddr, // laddr py_raddr, // raddr status, // status - pid); // pid + xf->xf_pid); // pid if (!py_tuple) goto error; if (PyList_Append(py_retlist, py_tuple)) @@ -238,7 +239,6 @@ int psutil_gather_unix(int proto, PyObject *py_retlist) { size_t bufsize; void *buf; int retry; - int pid; struct sockaddr_un *sun; char path[PATH_MAX]; @@ -286,6 +286,8 @@ int psutil_gather_unix(int proto, PyObject *py_retlist) { } while (xug->xug_gen != exug->xug_gen && retry--); for (;;) { + struct xfile *xf; + xug = (struct xunpgen *)(void *)((char *)xug + xug->xug_len); if (xug >= exug) break; @@ -293,8 +295,8 @@ int psutil_gather_unix(int proto, PyObject *py_retlist) { if (xup->xu_len != sizeof *xup) goto error; - pid = psutil_get_pid_from_sock(xup->xu_socket.xso_so); - if (pid < 0) + xf = psutil_get_file_from_sock(xup->xu_socket.xso_so); + if (xf == NULL) continue; sun = (struct sockaddr_un *)&xup->xu_addr; @@ -306,13 +308,13 @@ int psutil_gather_unix(int proto, PyObject *py_retlist) { goto error; py_tuple = Py_BuildValue("(iiiOsii)", - -1, // fd + xf->xf_fd, // fd AF_UNIX, // family proto, // type py_lpath, // lpath "", // rath PSUTIL_CONN_NONE, // status - pid); // pid + xf->xf_pid); // pid if (!py_tuple) goto error; if (PyList_Append(py_retlist, py_tuple)) diff --git a/psutil/tests/__init__.py b/psutil/tests/__init__.py index f14b1c98c..927e8cf64 100644 --- a/psutil/tests/__init__.py +++ b/psutil/tests/__init__.py @@ -930,7 +930,7 @@ def check_connection_ntuple(conn): # check fd if has_fd: - assert conn.fd > 0, conn + assert conn.fd >= 0, conn if hasattr(socket, 'fromfd') and not WINDOWS: try: dupsock = socket.fromfd(conn.fd, conn.family, conn.type) diff --git a/psutil/tests/test_connections.py b/psutil/tests/test_connections.py index c4d896eee..27822a807 100755 --- a/psutil/tests/test_connections.py +++ b/psutil/tests/test_connections.py @@ -132,10 +132,6 @@ def compare_procsys_connections(self, pid, proc_cons, kind='all'): raise # Filter for this proc PID and exlucde PIDs from the tuple. sys_cons = [c[:-1] for c in sys_cons if c.pid == pid] - if FREEBSD: - # On FreeBSD all fds are set to -1 so exclude them - # from comparison. - proc_cons = [pconn(*[-1] + list(x[1:])) for x in proc_cons] sys_cons.sort() proc_cons.sort() self.assertEqual(proc_cons, sys_cons) From 759b8a88ead6caf294aa45e84578056dc79440df Mon Sep 17 00:00:00 2001 From: Giampaolo Rodola Date: Thu, 18 May 2017 04:41:36 +0200 Subject: [PATCH 1090/1297] update HISTORY with #1079; give CREDITS to @glebius --- CREDITS | 2 +- HISTORY.rst | 4 ++++ docs/index.rst | 5 ++++- 3 files changed, 9 insertions(+), 2 deletions(-) diff --git a/CREDITS b/CREDITS index 515ba38d9..5483653a5 100644 --- a/CREDITS +++ b/CREDITS @@ -477,4 +477,4 @@ I: 1057 N: Gleb Smirnoff W: https://github.com/glebius -I: 1042 +I: 1042, 1079 diff --git a/HISTORY.rst b/HISTORY.rst index 8bf147f60..974af6171 100644 --- a/HISTORY.rst +++ b/HISTORY.rst @@ -22,6 +22,8 @@ - 1058_: test suite now enables all warnings by default. - 1060_: source distribution is dynamically generated so that it only includes relevant files. +- 1079_: [FreeBSD] net_connections()'s fd number is now being set for real + (instead of -1).
