Abstract socket pathnames must have a NULL character in the first position, but the second character must also be checked to differentiate an abstract name from the empty string. The address length must also indicate the length of the pathname because the kernel uses the entire address as the name, including NULL characters. ZMQ uses NULL-terminated strings for the address, so the abstract address length is the length of the string following the initial NULL byte plus 3; two bytes for the address family and one for the initial NULL character. --- src/ipc_address.cpp | 19 +++++++++++++++---- 1 file changed, 15 insertions(+), 4 deletions(-) diff --git a/src/ipc_address.cpp b/src/ipc_address.cpp index fb1acc86..e3d23fa4 100644 --- a/src/ipc_address.cpp +++ b/src/ipc_address.cpp @@ -51,11 +51,18 @@ int zmq::ipc_address_t::resolve (const char *path_) errno = ENAMETOOLONG; return -1; } +#if defined ZMQ_HAVE_LINUX + if (path_[0] == '@' && !path_[1]) { + errno = EINVAL; + return -1; + } +#endif address.sun_family = AF_UNIX; strcpy (address.sun_path, path_); #if defined ZMQ_HAVE_LINUX - if (*path_ == '@') + /* Abstract sockets on Linux start with '\0' */ + if (path_[0] == '@') *address.sun_path = '\0'; #endif return 0; @@ -73,10 +80,10 @@ int zmq::ipc_address_t::to_string (std::string &addr_) s << "ipc://" << address.sun_path; #else s << "ipc://"; - if (*address.sun_path) - s << address.sun_path; - else + if (!address.sun_path[0] && address.sun_path[1]) s << "@" << address.sun_path + 1; + else + s << address.sun_path; #endif addr_ = s.str (); return 0; @@ -89,6 +96,10 @@ const sockaddr *zmq::ipc_address_t::addr () const socklen_t zmq::ipc_address_t::addrlen () const { +#if defined ZMQ_HAVE_LINUX + if (!address.sun_path[0] && address.sun_path[1]) + return (socklen_t) strlen(address.sun_path + 1) + sizeof (sa_family_t) + 1; +#endif return (socklen_t) sizeof (address); } From 62e26b32424d17a3c589d7a30c4c19d554cc547f Mon Sep 17 00:00:00 2001 From: Brandon Carpenter Date: Mon, 7 Oct 2013 10:55:40 -0700 Subject: [PATCH 28/40] Add tests/test_abstract_ipc to .gitignore. --- .gitignore | 1 + 1 file changed, 1 insertion(+) diff --git a/.gitignore b/.gitignore index 80e94717..9d0a5563 100644 --- a/.gitignore +++ b/.gitignore @@ -69,6 +69,7 @@ tests/test_inproc_connect tests/test_linger tests/test_security_null tests/test_security_plain +tests/test_abstract_ipc tests/test*.log tests/test*.trs src/platform.hpp* From 433ea35b6c1af450279c887b5ec095dd4d72da21 Mon Sep 17 00:00:00 2001 From: Volodymyr Korniichuk <9173519@gmail.com> Date: Tue, 8 Oct 2013 00:40:30 +0300 Subject: [PATCH 29/40] Typo in type name "emTPy_slots_t" https://zeromq.jira.com/browse/LIBZMQ-565 --- src/ctx.hpp | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/src/ctx.hpp b/src/ctx.hpp index 9b6d8631..74733219 100644 --- a/src/ctx.hpp +++ b/src/ctx.hpp @@ -132,8 +132,8 @@ namespace zmq sockets_t sockets; // List of unused thread slots. - typedef std::vector emtpy_slots_t; - emtpy_slots_t empty_slots; + typedef std::vector empty_slots_t; + empty_slots_t empty_slots; // If true, zmq_init has been called but no socket has been created // yet.
